Copy of Rotational 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)
