Rotational Symmetry If, when you rotate a shape, it looks exactly the same as

Rotational Symmetry If, when you rotate a shape, it looks exactly the same as it did in its original position, then we say that the shape has rotational symmetry. A square • It looks exactly the same four times in a full turn. • It has rotational symmetry order 4.
