Alright, I'm working in a simple graphics library, graphics.h, which can be downloaded here:

I'm currently working on a simple game which required me to be able to have a center point, and rotational value (0-360) and then be able to draw a square that has sides with a length of exactly '5' around the point at the correct rotational value... how would I accomplish this? (I need the formula)

(Separating the points is preferable... I'd like to know where each corner is)

Thanks in advance...
