Rotational Symmetry: Test Your Knowledge

This video provides practice questions to test knowledge of rotational symmetry. It covers definitions, differences between rotational and reflectional symmetry, and how to determine the order of rotational symmetry for regular polygons. The video explains that a circle has infinite rotational symmetry and discusses specific cases like squares and shapes with rotational symmetry of order three and six.

Can a circle have rotational symmetry? Why or why not?

If a shape has rotational symmetry of order three, what angle can it be rotated by to make it appear unchanged?
