If none of those words mean anything to you (including myself), don’t worry, these lessons will help you understand them in no time! Let’s get started!

Top 9 Best Online Geometry Courses & Classes 2024

1. Geometry Fundamentals (Brilliant.org)

Geometry Fundamentals - Brilliant Org

Let’s start with a geometry fundamentals course from Brilliant.org. If you haven’t heard of Brilliant, they teach high school and college-level math, science, and coding through highly visual online courses and daily puzzles on trending topics.

This course will introduce you to angle axioms, perimeter and area calculation strategies, coordinate geometry, 3D geometry, and more. If you’re just getting started with learning geometry, this is the right course to start with. And you’ll want to make sure you have a bit of basic algebra under your belt, otherwise, you’ll want to brush up before diving in.

Once you’re into the course, you’ll start from the basics and become a proficient problem solver in everything from angles and lengths to area and volume. You’ll even get into the Pythagorean theorem and coordinate geometry. And to make it interesting, Brilliant.org presents its information through creative animations to ensure you move past rote memorization by truly mastering the underlying concepts.

Beyond this fundamentals course, Brilliant has an entire geometry track including:

Brilliant.org is a subscription program giving you access to their full 60+ subject catalog. You can push the monthly price down by selecting their annual or lifetime subscriptions options. And while not widely advertised, they also have a 7-day free trial if you want to sample some of the courses before you enroll.


  • 22 interactive lessons
  • Almost 150+ exercises
  • Perfect for high school students
  • Interactive App for both IOS & Android
  • includes access to in-depth Wiki

2. Online Geometry Tutors (Princeton Review)

Online Geometry Tutors - Princeton Review

Next up is an interesting concept I found in researching this article from test prep experts at Princeton Review. They’re not offering yet another online course. Instead, they have on-demand tutors that you can connect with whenever you have trouble with your stumped-on a problem or cramming for a test.

I included this because many times it’s not that you need a course to learn, but rather need help to ace the course you’re already taking. And these top-notch instructors are available to help 24/7, which is good because we know that high school students sometimes have demanding schedules which can lead to off-study times. And to make it extra convenient, there’s no appointment needed, meaning you get the help exactly when you realize you need it.

You might not have known that Princeton Review offered academic support online since they’re better known for the PSATSAT, and ACT testing prep courses. But they bring the same quality of instruction to help you get higher grades as they do to get higher test scores. And right now, they have a free trial to try out their geometry tutors with no risk.
