Summary
Mastering geometry on the ACT exam requires both visual and logical skills, emphasizing the importance of diagrams for problem-solving.
  • Always use or draw a diagram to visually represent geometry problems, enhancing understanding and solution strategies.
  • Incorporate given information and deduce additional details to annotate your diagrams, using symbols for perpendicular and parallel lines.
  • Extend or add lines in diagrams to facilitate calculations, and assign variables to lengths or angles for algebraic solutions.
  • Develop the skill to dissect diagrams, enabling a focus on both minute details and the broader picture, applying geometric properties universally.
  • Practice looking at both small and large elements within diagrams to understand and solve complex geometry problems effectively.
