Summary
The lesson focuses on tackling Geometry Questions in Data Sufficiency on the GMAT, 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.
  • Don't trust diagrams in Data Sufficiency questions as they may mislead or suggest relationships not guaranteed by the given information.
  • To find a specific length in a geometry question, you must be provided with another specific length measurement; angle measurements or ratio information alone are insufficient.
  • Developing visual imagination skills is crucial for envisioning different shapes that fit within a set of constraints, enhancing the ability to solve Data Sufficiency Geometry Questions effectively.
  • Practicing with geometric constraints by drawing multiple shapes that comply with them can significantly improve problem-solving skills for these types of questions.
  • Combining different pieces of information (e.g., angles and lengths) is often necessary to determine a unique geometric figure or to solve the question.

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.
