Circle Theorems - Part 1

This video introduces four circle theorems: the angle at the center is double the angle at the circumference, the angle in a semicircle is always 90 degrees, angles in the same segment are equal, and opposite angles in a cyclic quadrilateral add up to 180 degrees. The video includes explanations, examples, and practice questions to reinforce understanding. Viewers are encouraged to watch subsequent parts for more theorems involving tangents and chords.

What should you remember about the sides of a cyclic quadrilateral?
