Explain. The sum of the exterior angles is always 360o, so find an n-gon such that (n –2)180o = 360o. Solving this equation gives n = 4. A quadrilateral has the same sum for the measures of the interior angles and the measures of the exterior angles. 5-1, Triangles and Special Segments (Review): Notes, Worksheet 5-2, Triangle Sum and Exterior Angle Conjectures: Notes , Worksheet 5-3, Isosceles Triangles: Notes , Worksheet
