Circle Theorems 2

Performance Objectives

Students should be able to;

  1. Prove that the angles in the same segment of a circle are equal
  2. Angles in a semicircle is a right angle
  3. The opposite angles in a cyclic quadrilateral are supplementary
  4. The exterior angle is equal to interior opposite angles
