In this module, you'll learn all of the concepts, techniques and strategies needed to answer geometry questions on the GRE. In particular, this module covers:

  • Lines and angles
  • Isosceles and equilateral triangles
  • Right triangles
  • Special triangles
  • Similar triangles
  • Quadrilaterals
  • Circles: area & circumference
  • Circles: sectors & arcs
  • Circles: tangent lines
  • Circles: inscribed angles
  • Cylinders
  • Surface area & volume

Two ways to prepare

Beneath most of the video lessons below you’ll find a Related Resources box containing practice questions that are specifically related to the concepts covered in that lesson (e.g., the lesson on circles). With this lesson format, you have two study options:

  • Watch the video lesson first and then reinforce your learning by answering several related questions, or…
  • Tackle the practice questions first and watch the lesson only if you need help with the concepts the practice questions test

For more on this learning strategy, read the “How to Beat the GRE” section of our course overview page.

Practice from the Official Guide

Practice the skills and GRE-specific strategies you learned in this module by answering the following questions from the Official Guide to the GRE (1st or 2nd edition):

  • 111(4), 125(2), 146(2), 147(7), 149(12), 151(3), 153(11), 154(13), 155(1), 156(4), 158(11), 259(1-3), 260(4-9), 260(10), 261(11-13), 262(14) 

Note: The above practice questions are listed in the form page#(question#). So, for example, 111(4) represents question #4 on page 111.
