How do you order of rotation?

The order of rotation refers to the number of times a shape can be rotated to look the same within a full 360-degree rotation. For example, a square has an order of rotation of 4, as it appears identical at 0°, 90°, 180°, and 270°. To determine the order, identify the angles at which the shape maintains its appearance and count these positions. Shapes like circles have infinite order of rotation since they look the same at any angle.
