An Easy Tessellation

One of the easiest tessellations to produce uses a regular octagon and a square.
Use the two figures below to tessellate the entire plane.
Use the angle measurement tool to discover why these two figures will fully cover a plane with no gaps or overlaps.

Can you think of any other combination of shapes that will also tessellate a plane? Open a new GeoGebra windo and test your conjecture.
