Best Geometry Courses – Get Your Math Skills in Shape

Whether you’re an aspiring architect, a lifelong math whiz, a student seeking help for an upcoming exam, or you just want to review all of those formulas and theorems you vaguely remember going over in high school, geometry is worth learning. It’s one of the most deeply-studied fields of mathematics, having been researched for millennia. As such, it can be hard to determine where to begin when learning about this fascinating topic.

First, we’ll go over what characteristics matter in geometry courses, and then we’ll discuss the best ones available online. Next, we’ll give you some extra information to help you do well in the course(s) you choose, and then we’ll conclude by answering some frequently-asked questions about geometry courses.

Length

Most of our list’s courses have substantial runtimes. The shortest course clocks in at just over 3.5 hours, while the longest ones will ask for several hours of your time each week for about 1-4 months.

Also, be aware that some learning websites, specifically EdX and Coursera, only grant you access to their courses for a limited time. Paying for a Coursera class gives you 180 days to finish and earn the Course Certificate. If you get your certificate in that time, you’re fine, but if you don’t, you’ll have to pay the fee a second time to regain access to the course.

EdX courses have several deadlines as well. If you take one of them in audit mode, their free option, your access ends once the course’s listed duration has passed. To pass the course on the verified track, which is the paid option, you must finish it by the course end date. You’ll find all relevant deadlines on the “Course” tab once you enroll in the class.

Cost

Our list of courses comes from several learning-based websites, and they have different pricing policies:

• EdX lets you take its geometry courses for free, though it charges a fee to get a Verified Certificate. The Verified Certificate is a document that proves you finished the course, and you can add it to your resume, CV or LinkedIn profile to show potential employers. Paying the fee also lets you do the course’s graded assignments and keep your access to the class when it’s over.
• Coursera sometimes offers a free option (also called audit mode) for its courses. Audit mode lets you take the course, but you won’t get a Course Certificate when you finish it or be allowed to complete graded assignments. If you buy the course, you’ll have 180 days of access to those assignments, during which you can finish the class and get the certificate. Alternatively, you can buy a subscription to Coursera Plus ($59/month or $399/year), which gives you access to more than 90% of the site’s courses with graded assignments and certificates included. You can try Coursera Plus for free for 7 days if you haven’t already.
• Udemy charges a one-time fee for each of its courses. The prices of our list’s courses range from $20 to $160.
• Khan Academy offers its courses for free.

Curriculum

As we mentioned earlier, geometry is a well-studied area of mathematics, so there’s a lot to learn. Obviously, no single course can teach everything there is to know about the field, but that’s okay since you just need to find one that meets your particular needs. Some courses are suitable for beginners, while others cover more advanced topics or subfields of geometry, such as computational geometry. We’ll begin by discussing courses with a broader appeal before moving onto others that cover more niche topics.

1. Become a Geometry Master

---

Why we like it

If you’re a new geometry student who needs a study aid or you’re returning to the subject after a long absence, this course is for you. It clearly explains many basic geometry concepts and gives you lots of practice problems.

This class offers a great place to start learning geometry as it delivers many lessons throughout its 12 sections. You’ll learn about lines, angles, circles, triangles (which are discussed in several sections), quadrilaterals, perimeter, area, congruence, similarity, transformations, logic, proofs and three-dimensional geometry.

The vast amount of material covered is one of the course’s strengths, but the instructor deserves mention as well. Her easy-to-follow, step-by-step lessons are effective at demonstrating the right way to solve all kinds of problems discussed in the course. Plus, her friendly, positive attitude gives the course a welcoming feel.

The number of study materials provided is also worth mentioning. Each video lesson comes with notes that summarize the material covered in the video; it also provides any necessary formulas and shows some examples. Additionally, there are short quizzes after every lesson that you can use for practice, and you’ll find quiz answer keys, complete with explanations for every problem, at the start of each section. Each section also ends with a workbook that has more practice problems. Finally, there’s a final exam at the end of the course that lets you apply everything you’ve learned. Given everything that the course provides, you’ll have plenty of examples and practice problems for each lesson.

If this course has any negatives, it’s that it won’t hold much appeal for more advanced geometry students. It’s a great choice for anyone who’s just starting to learn the subject, but anyone wanting a course that dives into more complicated geometry topics should look elsewhere.

2. Introduction to Geometry

---

Why we like it

This course is a good choice for those who enjoy participating during class as it includes interactive lessons and discussion forums. It also covers lots of basic geometry concepts, so it’s an ideal place for newcomers to start learning.

This class is another solid option for those who are either just starting to learn geometry or haven’t practiced it for a while. It has 14 sections which cover lines, angles, triangles, polygons, quadrilaterals, circles, ellipses and transformations. Plus, you’ll learn how to calculate area, volume and surface area. Each section covers an important geometry concept, and consists of several topics. Each topic has an interactive lesson which periodically asks you to participate by answering questions and drawing shapes. Every lesson is accompanied by a review portion that asks you to complete a few more practice problems.

The course’s interactive elements are some of its greatest qualities. In addition to the aforementioned lessons, there’s a discussion forum you can use to talk to other students. If you’re having a hard time with a problem or have questions about the course, you can get help there. Each lesson also ends with a survey question so you can give feedback about your experience.

However, the course isn’t without its faults. You can only access the review area of the topics by paying the course fee, so you’ll have to look elsewhere for more practice problems if you want to take the free version.

3. Basic Geometry and Measurement

---

Why we like it

This class offers a wealth of instructional videos, notes, practice questions and tests to anyone learning introductory geometry. It’s also free, so you can either go through the whole course or just the parts that interest you.

This course presents a free one-stop-shop for anyone who wants to learn and practice introductory geometry. You can learn about lines, angles, shapes (including triangles, quadrilaterals and three-dimensional shapes), coordinate geometry, area, perimeter, volume, surface area, scale, mass, transformations, congruence, similarity and converting units of measurement. Plus, since Khan Academy’s classes are free, you can view as few or as many videos as you want.

Each section in the class is made up of several videos, and there’s almost always a page of notes that you can use to review the material that the section teaches. There are also lots of short quizzes throughout the class, in addition to a full course test at the end.

As for negatives, there are some aspects of basic geometry which this course doesn’t cover in much depth. Transformations, congruence and similarity, for instance, are introduced in the class’s final unit, but if you want to learn more about them you’ll have to take another Khan Academy course. Also, the lessons on mass and units of measurement, while possibly intriguing to math enthusiasts, may not interest those who just want a geometry review.

5. Geometry Basics to Advanced

---

Why we like it

This course offers a deep dive into many basic geometry concepts, taking time to thoroughly explain each one. It’s best for anyone just starting to learn the subject or who is returning to it after some time away.

If you’re the kind of person who prefers longer, more detailed explanations when learning a new subject, then this class is for you. You’ll learn about lines, planes, angles, polygons, triangles, quadrilaterals, circles, basic trigonometry, coordinate geometry, three-dimensional geometry, shapes inscribed within other shapes, and the graphical division method.

It helps that the instructor explains each principle in extensive detail while keeping the lessons easy to follow. Plus, there are practice questions all throughout the course, so you’ll have plenty of opportunities to practice your new skills. Answers to the practice questions are also given. The course concludes with a 20-question quiz that will have you apply everything you’ve just learned.

The course’s only notable drawback is that it won’t offer much instructional value to anyone seeking an intermediate or advanced course since it’s mostly made for newer students.

6. Master Geometry: Full Curriculum With Practice

---

Why we like it

Do you plan on taking higher math classes once you’ve got geometry down? If so, then this course is for you. It teaches geometry essentials while simultaneously preparing you for more advanced courses.

Geometry is often a required course in high school math curriculums and is usually followed by classes on precalculus, trigonometry, or advanced algebra. Given that geometry is just one phase of most students’ math educations, it makes sense to also get ready for future classes. Luckily, this course focuses on covering basic geometry as well as complex topics like proofs, mathematical logic and beginner’s trigonometry, which will prove relevant in those later classes.

The instructor is another great selling point for the course. He demonstrates the formulas and concepts with plenty of examples and explains them in an easy-to-follow manner. Throughout the course, he’ll walk you through triangles, circles, polygons, coordinate geometry, three-dimensional geometry, congruence, similarity, proofs, math logic and basic trigonometry.

The course’s only serious flaw is its low amount of practice problems. There are a handful of problems provided after some lessons, but other classes give students a lot more of them. Also, unlike some other geometry courses, this class doesn’t have an introductory section covering lines and angles. Given that you need to be familiar with them to understand the topics the course teaches, they should’ve been covered first.

7. Geometry – Math – GMAT/GRE/SAT/ACT/CAT

---

Why we like it

Are you experiencing the unique dread of an upcoming college or graduate admissions exam? Are you struggling with geometry review? If so, this course is here to help you get the geometry portion of your test prep on track.

Anyone who has ever had to prepare for a standardized or admissions test knows it’s important that you practice your math skills. Every one of these kinds of tests includes a math or quantitative skills section, and geometry is often part of that section. If geometry is giving you a hard time as you study for your exam, then this course is for you.

The class covers lines, angles, triangles (with extra lessons on triangle congruency and similarity), quadrilaterals, and circles (with extra lessons on circle tangents). For the most part, the course is divided into small, manageable chunks with each video focusing on a single theorem or principle, though there are some longer videos as well. Each section of the course also has practice questions that quiz you on the material you just learned.

However, the course does have some drawbacks. It doesn’t teach prisms or three-dimensional shapes, so you’ll have to look elsewhere for a review of concepts relating to those figures. Also, keep in mind that geometry questions are only one type of math problem found on admission exams, and these tests cover several subjects in addition to mathematics. All this is to say that while this course can help you improve your geometry for an exam, it shouldn’t be your only form of test prep.

8. Computational Geometry

---

Why we like it

If you’re interested in computer science and you want to learn how program geometric algorithms, consider this course. It’s a great introduction to a new field of geometry.

As we mentioned earlier, geometry has been studied for millennia, but in that time, a number of subfields have emerged. One of these newer areas of study is computational geometry, which began in the 1970s and entails creating algorithms to solve problems that have geometric inputs and outputs. As such, the field is a crossover between geometry and computer science, and this course requires you to have a working knowledge of C++, data structures and algorithms.

The goal of the course is to give students a solid understanding of computational geometry so they can apply it in their own projects when necessary. Since computational geometry is used in robotics, computer graphics, computer-aided design and manufacturing, geographic information systems, and other fields, professionals in many areas may benefit from learning it. Specifically, the course teaches geometric algorithms including polygon decompositions, Voronoi diagrams, and Delaunay triangulations.

However, as you can likely tell from our description of the course, its appeal is limited to a certain niche. If you’re not interested in this particular subfield of geometry, then this class won’t be of interest.

9. Computational Geometry

---

Why we like it

This class is great for anyone who wants to learn all the ways in which computational geometry impacts technological fields and how to create algorithms to solve problems in those fields.

If you’re a computer science enthusiast and already well-versed in geometry, then this could be the course for you. It’ll show you how to make a number of different algorithms to solve problems in fields such as computer graphics and geographic information systems. Plus, you’ll learn the pros and cons of each algorithm so you can determine which one you should use when you encounter a computational geometry problem.

Specifically, this course covers how to test point inclusion in a polygon, use convex hulls to approximate finely-shaped objects, use intersecting line segments to make geographic information systems more responsive to user requests, use polygon triangulation to process 3-D scenes made with computer graphics, and improve database queries. It helps that each unit has a few practice programming exercises that let you apply its lessons.

Also, be aware that this course has some prerequisites. Since this is a computational geometry class, you’ll need a basic understanding of at least one programming language as well as a solid grasp of mathematical proofs.

Lastly, the course has some drawbacks to consider. The video editing hinders the viewing experience as the recording frequently cuts between the instructor and the whiteboard. In addition, the instructors use PowerPoint presentations to teach the algorithms, which may disappoint those who’d prefer to see dry runs and examples of algorithms in action.
