Do you have a specific application in mind? Maybe you could tell us what you are to do so we can guide you with understanding.
I wanted 135 to be 45 and 225 to be 45 and 180 to be 90 something like that,I know there's a formula how to get those.But I just can't figure it out,so please help =).I just wanted any angle to be something between 0 to 90,so angle 91 will become 1 so on and so forth.
135 and 45 are supplementary angles
135 + 45 = 180
and complementary angle og 45 is 45
45 + 45 = 90
angle < 90 is acute
angle 90 = right angle
abgle > 90 is obtuse
angle = 180 is straight angle
angle > 180 is reflus angle
sum of all angles at a point is 360°
