In this lesson, the third in a four-part series from Illuminations titled “Symmetries and Their Properties — Part 1: Rotational Symmetry,” students investigate the relationship between rotations and the symmetry in a figure or a design. They use an interactive Java applet to illustrate rotational symmetry and investigate cyclic designs and point symmetry.
