This document provides instructions for using computer and iPad applications to perform geometric transformations including translations, rotations, reflections, and coloring of shapes. It describes how to select shapes, copy and paste them, slide them to form tessellations, flip them vertically, rotate them 180 degrees, and change their colors. Hints are provided like holding shift to select multiple shapes at once and using the arrow keys or swiping to nudge shapes in small increments. Examples of tessellations by the artist M.C. Escher are also referenced.
