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.


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.


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.


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.

  • Teaches basic geometry in addition to proofs, math logic, and introductory trigonometry

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.


  • Covers basic geometry and some intermediate concepts
  • Teaches concepts that will be necessary in future math classes
  • Instructor is good at explaining geometry principles in an understandable way


  • Doesn’t offer as many practice problems as other courses
  • No introductory section about lines and angles

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

  • Practice questions are included in each section

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.


  • Helps you prepare for geometry questions on standardized tests
  • Comes with dozens of practice questions
  • Teaches most basic geometry principles


  • Prisms and three-dimensional shapes aren’t covered
  • Only helps you with a small portion of most standardized tests

8. Computational Geometry

  • Course Highlights
  • Skill Level: Advanced
  • Taught by a professor from Tsinghua University
  • Focuses on how computer science and algorithms can be used for advanced 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.


  • Introduces you to a new area of study within geometry
  • Knowledge from the course can be used in many different fields
  • Learn how to make several kinds of geometric structures and algorithms


  • Course isn’t for anyone who’s not interested in computer science

9. Computational Geometry

  • 4 hours/week for 5 weeks (recommended) Free or $49 for Certificate Our rating  
  • Course Highlights
  • Skill Level: Advanced
  • Taught by instructors from Saint Petersburg State University
  • Focuses on how algorithms are used in many fields

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.


  • Teaches how to make different algorithms to complete various tasks
  • Students learn what each algorithm is and isn’t good for
  • Comes with programming exercises you can use for practice


  • Video editing is somewhat distracting
  • Reliance on PowerPoint slides for teaching may not be to everyone’s taste


Yes! There are several websites that provide free geometry lessons. One option is Khan Academy, which offers you plenty of geometry video lessons, notes, practice problems, quizzes and tests, all for free. We discussed their basic and high school geometry courses earlier in this article.

Geometry is used in many kinds of jobs. Professionals who can expect to make regular use of geometry include but aren’t limited to architects, fashion designers, robotics and mechanical engineers, surveyors, cartographers, CAD engineers or drafters, urban planners, animators, math teachers and mathematicians. If any job requires knowledge of shapes, angles and/or dimensions, you can safely assume you’ll need some geometry skills to do it well.

The GMAT, GRE and SAT each include geometry questions in their quantitative/mathematics sections, but only a minority of problems in those sections will test you on this subject.

The GMAT tests algebra and arithmetic more than geometry, though it still shows up both in dedicated geometry questions and some word problems. Similarly, the GRE tends to have a handful of geometry-specific problems, and you may see geometry concepts pop up in data interpretation, algebra or word problems. Lastly, the SAT is likely to include only 3-6 geometry questions.

The ACT and CAT place a greater emphasis on geometry. Around 40-55% of the ACT’s math section consists of geometry and trigonometry. Meanwhile, the CAT’s Quantitative Aptitude section has 34 questions, of which 9-10 concern geometry and trigonometry.

Everything You Need to Know to Succeed in Your Online Geometry Course

Prerequisite Math Knowledge

Even the more beginner-friendly courses on our list will require you to have some basic knowledge of mathematics, including equation-solving. Luckily, this prerequisite won’t be a problem for most people. Essentially, if you know how to add, subtract, multiply and divide, and you can solve the kinds of equations you’d see in an introductory algebra class, you’re good to go. If you’re in need of a math review, check out our list of the best free online math courses.

However, our list’s more advanced courses come with some additional prerequisites. For the computational geometry courses, you’ll need some computer programming knowledge and, depending on the course, an understanding of either mathematical proofs or data structures and algorithms.
