Summary
The content provides a comprehensive overview of effective geometry strategies for the GMAT exam, emphasizing the importance of visual and logical skills in solving geometry problems.
  • Geometry is primarily visual and demands both visual and logical skills for problem-solving.
  • Always draw a diagram to better understand and mark up with known and deducible information.
  • Look for similar triangles, especially when more than two triangles are involved or parallel lines are present.
  • The Pythagorean Theorem is widely applicable in various scenarios, including finding the length of altitudes or diagonals.
  • Familiarity with Pythagorean triplets and the properties of special right triangles (30-60-90 and 45-45-90) can provide significant advantages.
  • Understanding the rules about angles, especially in circles, is crucial for solving geometry problems on the GMAT.
  • Practicing the recognition of geometric figures in everyday life can enhance the ability to spot geometric patterns, a skill valuable for the GMAT.
