First off to make sure its a square you'll want to make sure that the two diagonals of the square have the same length. Easiest way to make sure its a square.

Think about pythagorus to do this. I could give you a formula, but from what I have read you wouldn't understand it. Have a think about pythagorus and how you can use it to find the length of the diagnols, then sub in the (x,y) values to your working...

If you want the square to be "flat", as in not on an angle, Y1 will equal Y2, and X1 will equal X3, with the coordinates being

(x1,y1) (x2,y2)
(x3,y3) (x4,y4)

Hope that helps.
