Rectangle

You are not allowed to move points A and B. You must move points C and D until ABCD is a rectangle (or square), with 4 right angles. Write down the positions of C and D. After you have done that, find a different solutions for C and D. When you are finished, you should have made one RECTANGLE and one SQUARE.
