Fake Squares

Mr. Lewis
Which is the real square? Only one of the quadrilaterals are actually squares. The rest are impostors! Instructions Move the vertices around in each quadrilateral to discover the true nature of each quadrilateral. (Not all points can be moved but be sure to try and move all four points before coming to a conclusion.) If you need room, you can hide any quadrilateral by unchecking it's box. You can also move the entire shape.
