Well in my last post I guessed that Mrs. Petit's picture of the week was a Tessellation. Now I think I'm going to discuss what that is and even if I am wrong about what the picture is I am hoping Mrs. Petit will give credit for trying.A tessellation is a combination of one or more shapes that, when repeated, cover a surface with no gaps and no overlaps. We created one of these in Pre-AP Geometry my Sophomore year when we decorated a Valentine's Day card. I used a lightning bolt while some of my fellow classmates used crosses, boots, and even a penguin. Well, the word tessellation came from the Latin word "tessella", meaning a small square tile often used in ancient Roman mosaics. A tessellation is often called a tiling, which you can see in a modern day checkerboard. With some research I also learned that it is possible to Tessellate non-plane surfaces, such as a sphere. My picture is a spherical version of Mrs. Petit's picture of the week.
