In XNA, when you have a rectangular sprite that doesnt rotate, it's easy to get its four corners to make a hitbox. However, when you do a rotation, the points get moved and I assume there is some kind of math that I can use to aquire them.

I am using the four points to draw a rectangle that visually represents the hitboxes.

I have seen some per-pixel collision examples, but I can forsee they would be hard to draw a box/'convex hull' around. I have also seen physics like farseer but I'm not sure if there is a quick tutorial to do what I want.
