Confirm Translational Symmetry --- Totally Tessellated @ http://library.advanced.org/16661/
Instructions: Print two copies of page (preferably on lightweight or tracing paper) and then close this window. Line up the two pages. Then, keeping the bottom page steady, translate the top page in the direction and magnitude indicated by the arrow shown below. See that the copy matches the original. Thus, this tessellation has translational symmetry.
