WebFor ABC shown above, ∠CAD is the exterior angle for ∠A and ∠B and ∠C are the two remote interior angles. We know that ∠CAB + ∠B + ∠C = 180°. Also, ∠CAB and ∠CAD form a straight angle, so ∠CAB + ∠CAD = 180°. Since both sums equal 180°: ∠CAB + ∠CAD = ∠CAB + ∠B + ∠C ∠CAD = ∠B + ∠C The same can be shown for any exterior angle of any triangle.
