Rotational Symmetry If a shape can fit exactly into itself after a certain rotation (not a full one) about a fixed point (called centre of rotation) then it is said to have rotational symmetry. The angle of turning during rotation is called the angle of rotation. For example, a square has a rotational symmetry.Point … [Read more...] about How do you figure out Rotational Symmetry?
