Duplicate Diagonal Pattern ---- Totally Tessellated @ http://library.advanced.org/16661/
Instructions: Print this page and then close this window. This is the semiregular tessellation 3.12.12. On each dodecagon (12 sides), repeat the diagonal pattern that has already been drawn for you. (Note that not all diagonals of the dodecagon have been drawn in.) Leave the equilateral triangles as they are. After you are done, color the resulting tiling any way you want! (Ignore the original tessellation after you are done.)
