summary
mastering geometry on the sat requires both visual and logical skills, emphasizing the importance of diagrams for problem-solving.
  • always use or draw a diagram when tackling geometry problems to engage the visual part of your brain.
  • label your diagrams with given information and anything you can deduce, using symbols for perpendicular and parallel lines.
  • consider extending lines or adding new ones to facilitate calculations, and assign variables to lengths or angles as needed.
  • develop the ability to dissect diagrams, looking at both the details and the bigger picture to apply geometric properties effectively.
  • practice problems are essential for honing the skill of switching between focusing on small details and understanding the overall shape.
