How To Find The Order Of Rotational Symmetry

This video introduces rotational symmetry, defining it as the symmetry of a shape when rotated around its center. The order of rotational symmetry is the number of times a shape looks identical within a 360-degree rotation.

Using a square as an example, the video demonstrates how to find rotational symmetry. By rotating the square, it is shown to look the same in four different positions, giving it an order of rotational symmetry of four.

If a shape only appears the same in one position after a full rotation, it has no rotational symmetry, or an order of one.

The video provides further examples of shapes with varying orders of rotational symmetry and concludes with practice questions for viewers to test their understanding.
