This document discusses polygons and tessellations. It defines regular and non-regular polygons and explains that a tessellation is a repetitive pattern of polygons that fit together without overlaps or gaps. Examples are provided of classifying polygons by number of sides and determining which shapes can form tessellations. Students are asked to complete examples of identifying regular and irregular polygons, determining angle measures, and finding real-world examples of tessellations.
