Science Buddies: "Ask an Expert"

What is Tessellation? I am trying to figure out different number of ways to tile an infinite two-dimensional surface with spidron- based shapes.

Hello.

Tessalation is simply laying the same shape in patterns over and over to cover a floor without overlap or gaps. You can read more here, and a simple Google search will provide plenty more websites to study.

If you have any more questions, feel free to write back. This can be a fun way to create artwork.
Good luck!
