Escher's "Lizards" Tessellation

M.C. Escher was the master of transforming polygonal tessellations into non-polygonal works of art. The connection between the symmetries of the underlying polygonal tessellation, and the symmetries of the transformed tessellation can be traced back to the transformations used to create the non-polygonal tile.

Before moving any of the sliders, examine Escher’s "Lizards" tessellation below and answer the following questions:

1. Describe the symmetries of the “Lizards” tessellation.

2. What is the tessellation’s underlying polygonal structure

3. What shape is the tile formed from? What specific transformation could be used to move the tile into the spot of another lizard? How was the tile formed?
