A symmetry operation has to do with moving a shape through space in various ways and repeating the shape. The pattern is created through repetition. In rotational symmetry, shapes are moved in equal distances around an imaginary axis. For example, flower petals arrayed around the center of the blossom have rotational symmetry.
Circle dances performed by a group are the most obvious example of rotational symmetry. But a soloist can also create rotational symmetry simply by making a series of quarter turns and repeating an action or pose.… Read More
