Question

what is the sum of the exterior angles of a triangle? Use the fact that the sum of the interior angles of a triangle is 180° and the fact that the measure of a straight angle is 180° to justify your answer. ? Each pair of corresponding interior and exterior angles forms a straight angle, so the sum of the exterior angles is $3 \times (180^\circ - 180^\circ) = 0^\circ$. ? Each pair of corresponding interior and exterior angles forms a straight angle, so the sum of the exterior angles is $(3 \times 180^\circ) - 180^\circ = 360^\circ$. ? Each pair of corresponding interior and exterior angles forms a straight angle, so the sum of the exterior angles is $(3 \times 180^\circ) + 180^\circ = 720^\circ$. ? Each pair of corresponding interior and exterior angles forms a straight angle, so the sum of the exterior angles is $3 \times (180^\circ + 180^\circ) = 1080^\circ$.
