Symmetry is a way that units of pattern are organized. A figure is symmetric if you can pick up a copy of it, move it to a new location or orientation, and set it down so that it exactly matches. There are twenty-four two-dimensional symmetries. Here we describe three: mirror or reflection symmetry; translation symmetry and rotational symmetry.
