Key Topics to Revise

1

Basic Geometrical Elements

  • A point has no length, width, or thickness — it only shows a position.
  • A line extends infinitely in both directions and is denoted with arrows on both ends.
  • A ray starts from a fixed point and goes infinitely in one direction.
2

Angles and Their Types

  • An angle is formed when two rays start from the same point (vertex).
  • Angles are measured in degrees (°).
  • A full rotation is 360°, a straight angle is 180°, and a right angle is 90°.
3

Special Angle Pairs

  • Complementary angles add up to 90°.
  • Supplementary angles add up to 180°.
  • When two lines intersect, adjacent angles are supplementary, and vertically opposite angles are equal.
