The sum of the measures of the exterior angles of a convex polygon, one angle at each vertex is = 360 ° We can add the measures of all exterior angles of the above pentagon and the sum can be equated to 36 0 °. The Consecutive Interior Angles Theorem states that if two parallel lines are cut by a transversal, then consecutive interior angles are supplementary (= 180°) Notice that the two exterior angles shown are supplementary (add to 180°) if … Each pair of these angles are outside the parallel lines, and on the same side of the transversal. My self Sivaramakrishna Alluri. Cloudflare Ray ID: 614db089b8e400c7 If you count one exterior angle at each vertex, the sum of the measures of the exterior angles of a polygon is always 360°.
