DS Geometry Questions



Summary
The lesson focuses on tackling Geometry Questions in Data Sufficiency on the GRE, emphasizing the importance of not trusting diagrams, the necessity of being given a length to find a length, and the value of using visual imagination to envision various shapes.
  • Do not trust diagrams in Data Sufficiency questions as they may not accurately represent the geometric information given in the statements and can lead to unjustified assumptions.
  • To find a specific length in a Data Sufficiency Geometry question, you must be given another specific length measurement; angle measurements or ratio information alone are insufficient.
  • Developing visual imagination skills is crucial for envisioning the different shapes that could fit a given set of constraints, which is essential for answering Data Sufficiency questions effectively.
  • Practicing with geometric constraints by drawing as many different shapes as possible that are consistent with those constraints can significantly improve problem-solving skills in geometry.

The GMAT in its current form will be offered through early 2024. Starting in Q4 of 2023, a new, shorter version of the exam called the GMAT Focus will become available.

This lesson applies to the current GMAT only since the GMAT Focus edition does not test Geometry.

Please see the lesson "New GMAT Focus Edition Coming in Q4 2023" for more details about the Focus edition.
