In this worksheet we will investigate the rotational symmetry of a regular polygon. Each of the polygons is regular (equiangular and equilateral) and 1 exterior angle is shown.

1) Move the slider and describe what happens to each of the 3 regular polygons.
2) What conjecture can you make about the rotational symmetry of a regular polygon? (relate it to the exterior angle)
