Key Topics to Revise

1

Basic Concepts - Points, Lines, and Rays

  • A point is a location with no dimensions, represented by capital letters (A, B, C)
  • A line extends infinitely in both directions and is named using two points or a small letter
  • A line segment is the shortest path between two points
2

Angles and Their Types

  • An angle is formed by two rays starting from a common point (vertex)
  • Angles are measured in degrees (°)
  • Right angle = 90°, Straight angle = 180°
3

Pairs of Angles

  • Adjacent angles share a common vertex and side
  • Complementary angles sum to 90°
  • Supplementary angles sum to 180°
4

Parallel Lines and Transversals
