Geometry Strategies - Part I

Mastering geometry for the GRE requires both visual and logical skills, emphasizing the importance of diagrams for problem-solving.
  • Always create or redraw diagrams to visually process and solve geometry problems, marking them with given and deduced information.
  • Use symbols and notations like squares for perpendicular and arrows for parallel lines to enhance understanding and problem-solving efficiency.
  • Extending lines or adding new ones in diagrams can facilitate calculations, and assigning variables to lengths or angles allows for algebraic solutions.
  • Develop the skill to dissect diagrams, looking at both the details and the bigger picture, to apply geometric properties effectively.
  • The ability to switch perspectives between detailed and broader views of diagrams is crucial for solving complex geometry problems.
