Rotational Symmetry

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