Geometry Courses

Use our online geometry courses and study guides to tackle difficult subjects covered in your own high school class. Engaging video lessons and a self-paced course format make it easy to master geometric proofs, the properties of shapes and the formulas used to calculate their dimensions.

How It Works

Choose a geometry course: We offer geometry courses and study guides for high school students as well as adult learners trying to earn their GED.
Watch fun video lessons: Video illustrations provide you with the perfect format for studying the dimensions of shapes.
Take practice quizzes and tests: Keep each lesson's problem-solving steps and vocabulary terms fresh in your mind with multiple-choice quizzes and practice exams.
Ask our experienced geometry teachers for help: Our geometry experts are available to answer all of your course questions.

Who Our Courses Are For

Students looking for geometry textbook supplements and tutoring resources
Students trying to prepare for state end-of-year exams
Adult learners preparing for the math portion of the GED
Teachers interested in course materials aligned with Common Core standards

Why Our Courses Work

Self-paced instruction: Breeze through introductory geometry concepts or spend some extra time working with geometric formulas and proofs. You can take as long as you need to complete each lesson.
Sample problems: You'll get plenty of opportunities to apply the problem-solving steps discussed in the instructional videos. Sample problems can be found in the quizzes and practice tests, in addition to the lessons themselves.
Progress tracking: If you're preparing for a big exam, our course tracking feature can help make sure you complete all of the lessons and quizzes in time for test day.
