How to Find the Order of Rotational Symmetry

This video tutorial explains rotational symmetry and how to determine the order of rotational symmetry for shapes. It provides examples, such as a square, to illustrate the concept and includes practice questions to reinforce learning. Rotational symmetry is when a shape looks the same after being rotated around its center. The order of symmetry is the number of times a shape appears identical during a full 360° rotation. The video encourages using tracing paper to test symmetry and highlights that shapes with no rotational symmetry have an order of one.
