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 got rotational symmetry . This square has got rotational symmetry. It looks exactly the same four times in a full turn. It has got rotational symmetry order 4 .

Pentominoes:

Pentominoes A pentomino is made out of five squares that are connected along at least one edge. These are NOT pentominoes. Here is an example of a pentomino. How many different pentominoes can you find? Click here to return to line symmetry.

7-Pin Polygons:
