WebThe measure of an exterior angle of a triangle equals the sum of its two remote interior angles. For 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°: WebThis is a foldable activity to classify triangles by Angle Measure and their characteristics. 1.
