Circle Theorems : Cyclic Quadrilateral Investigation

Cyclic Quadrilateral Exploration Investigation. Move the points around to recognise any patterns.

Is there any pattern with the opposite angles? What do all the angles add up to? What do opposite angles add up to? Is it possible to make a square? Express this pattern algebraically using a general cyclic quadrilateral.
