Worksheet: Tessellations by Polygons

In this worksheet, we will practice identifying which polygons can form a tessellation and the geometric transformations applied to it.


Yasmine wants to tile her bathroom floor using two colors of regular pentagonal tiles that are of identical sizes as shown in the picture. As the pentagons do not tessellate, she also needs to buy some tiles to go in the empty spaces.

The additional tile needs to fit exactly into the empty space. What would be the size of the acute angle in this tile?

What would the size of the obtuse angle in the tile be?
