6-1 The Polygon Angle-Sum Theorem
DODEA Standard
G.1.1: Demonstrate understanding by identifying and giving examples of undefined terms, axioms, theorems, and inductive and deductive reasoning;
G.3.4: Determine the sum of both the interior and exterior angle measures of a polygon;
G. 3.5: Determine and use measures of sides and of interior and exterior angles of triangles, quadrilaterals, and other polygons to classify figures, develop mathematical arguments about geometrical relationships, and solve problems.
Objective
To find the sum of the measures of the interior angles of a polygon
To find the sum of the measures of the exterior angles of a polygon
