Polygons: Rotational Symmetry

A regular polygon has all sides and angles equal.

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.

Conclusion for this

regular polygon.The order of rotational symmetry of a regular hexagon is 5.

Can we therefor say that the order of rotational symmetry of any regular polygon is equal to its number of sides?

5 This is equal to the number of sides of the hexagon.
