This is basic Pre-Algebra geometry, and a quick google would have set you up, but I guess I'll tell you:
In a geometric rotation, every point is multiplied by negative one. Example:
A(1,1)
A(1 * -1, 1 * -1)
New A(-1,-1)
So you essentially multiply the x and y coordinate of every point in your shape by negative 1. It can be expressed in a matrix by:
A[2,3]
A[-2,-3]
EDIT:
Also, just set it up so whatever you do to one object you do to the other, this is called Baking if I'm correct. Better suited for the Math forum however.
