  1. Polygons:

  2. If we turn a polygon about its centre (centre of rotation) we find that there is more than 1 position in which the shape is the same as its starting position. Polygons: Rotational Symmetry A regular polygon has all sides and angles equal.

  4. Polygons: Rotational Symmetry The order of rotational symmetry of a regular hexagon is 5. 5 1 This is equal to the number of sides of the hexagon. Conclusion for this regular polygon. 4 2 Can we therefor say that the order of rotational symmetry of any regular polygon is equal to its number of sides? 3
