5.) What is a tessellation? Include a picture of a tessellation.

According to the site listed below, a tessellation is "a covering of an infinite geometric plane without gaps or overlaps by congruent plane figures of one type or a few types." There are only two regular tessellations (tessellations made of one type of regular polygon). These are a triangle tessellation, a quadrilateral tessellation, and a hexagon tessellation.
