Additional Practice

Each of the above video lessons features a Reinforcement Activities box containing practice questions that are specifically related to the particular concepts covered in that lesson (e.g., the lesson on Right Triangles). On the other hand, the links below will take you to practice questions that test a wide variety of questions under the general topic of Geometry. Given this, you may find it beneficial to work on the questions below AFTER you’ve mastered the content in the Geometry module above.

- Official GMAT questions about Geometry - Problem Solving

- Official GMAT questions about Geometry - Data Sufficiency
