WebbExterior Angle Theorem. The exterior angle theorem states that when a triangle's side is extended, the resultant exterior angle formed is equal to the sum of the measures of the two opposite interior angles of the triangle. The theorem can be used to find the measure of an unknown angle in a triangle.To apply the theorem, we first need to identify the … WebbExplore: 1. In each polygon, draw all the diagonals from one vertex. Notice that the diagonals divide the polygon into triangles. 2. By the Triangle Angle Sum Theorem, the sum of the interior angles of a triangle is . Use this theorem to complete the table.
