Today's lesson involved the second aspect of symmetry that we will study: rotational symmetry. We went over how to determine the order of a rotation and the value of the angles that an object must rotation through in order to map onto itself. We went through several pictures to display these concepts, as well as showing what point symmetry looks like.
