We know that, An angle of rotation is the measure of the amount that a figure is rotated about a fixed point called a point of rotation. The order of rotational symmetry of a shape is the number of times it can be rotated around a full circle and still look the same. The centre of rotation is a point about which a plane figure rotates. This point does not move during the rotation.
