Let’s discover some more circle theorems so that we can solve all types of geometrical puzzles.
We discovered these 4 theorems in part 1:
Angle at the centre is double the angle at the circumference
The angle in a semi-circle is 90 degrees
Angles in the same segment are equal / Angles subtended by

If we don't have the vertical height of a triangle, then we can find the area of the triangle using 1/2absinC.
In this video we are going to discover where this formula comes from. The formula is based on area = 1/2 base X height and a
