An angle plus it's complement is equal to 90.   Let's call the angle X.   It's complement is therefore X also.   And the sum of them is 90, so 2X = 90 and X = 45.

Well, two angles are complementary if they add to 90°.

If an angle x is the same as its complement then that means that x+x = 90°
From there, you can easily solve to find the value of x.

Edit: Gah, pi man beat me. smile


Why did the vector cross the road?
It wanted to be normal.
