Grade 6 - Shape and Space
Standard 6.SS.5 - Practice identifying regular and irregular polygons.
Included Skills: Geometry
Describe and compare the sides and angles of regular and irregular polygons. • Sort a given set of 2-D shapes into polygons and non-polygons, and explain the sorting rule. • Demonstrate congruence (sides to sides and angles to angles) in a regular polygon by superimposing. • Demonstrate congruence (sides to sides and angles to angles) in a regular polygon by measuring. • Demonstrate that the sides of a given regular polygon are of the same length and that the angles of a regular polygon are of the same measure. • Sort a given set of polygons as regular or irregular, and justify the sorting. • Identify and describe regular and irregular polygons in the environment.
