summary
mastering geometry for the gre requires both visual and logical skills, emphasizing the importance of diagrams for problem-solving.
- always use diagrams when solving geometry problems, drawing or redrawing them as necessary to include given and deduced information.
- utilize symbols and notations like squares for perpendicular and arrows for parallel to enhance understanding and problem-solving efficiency.
- extend lines or add new ones to facilitate calculations, and consider assigning variables to lengths or angles for algebraic solutions.
- develop the ability to dissect diagrams, looking at both the details and the bigger picture to apply geometric properties effectively.
- practice problem-solving by both focusing on small details and considering the entire geometry to find solutions efficiently.
