"Mirroring" an angle

Question

I need to obtain the supplement of an angle.

Exactly what I need to do is to implement some kind of code that mirror the angle, let's say, I have 45 degrees -> 135, another example: 80 ->100, 0 degrees -> 180, and so on.

Answer 1

I think you're after 180 - yourAngle.

Your examples:

• 45 degrees: 180 - 45 = 135
• 80 degrees: 180 - 80 = 100
• 0 degrees: 180 - 0 = 180
