Trigonometric identities of 180 - x

Instruction

Drag the black point marked 'A' to change the angle θ. Study how the point A' which is on the terminal side of 180o - θ change as θ change. We are going to study the relationship between trigonometric function of θ and 180o - θ.

What is the relationship between the coordinates of A and coordinates of A' in the graph trigonometric fucntion of θ and 180° - θ?
