Form 3 Mathematics – Circle Theorems (Full Derivations & Examples)

In this video, I take you through important circle theorems step by step, making it easier for Form 3 students to understand and apply them in exams. I carefully derive each theorem and then provide worked examples to show how they are used in solving mathematical problems.

What’s covered in this lesson:
1. Angles in the same segment are equal
2. Angle at the center is twice the angle at the circumference
3. Angle in a semicircle is 90°

This tutorial is ideal for Form 3 students preparing for tests, MSCE exams, or anyone who wants to strengthen their foundation in Geometry.

Part II will cover the remaining theorems in book 3 which are (1) opposite angles in cycling quadrilateral are supplementary and (2) the exterior angle of cyclic quadrilateral is equal interior opposite angle.

Part III will deal with book 4 circle theorems, tangent of a circle.
