Question

state the exterior angle property of a triangle

Answer 1

Theorem 1: Angle sum property oftriangle states that the sum of interiorangles of a triangle is 180°. Proof: Consider a ∆ABC, as shown in the figure below. To prove the aboveproperty of triangles, draw a line parallel to the side BC of the giventriangle. Thus, the sum of the interiorangles of a triangle is 180°

Answer 2

Exterior angle of triangle states that the sum of the corresponding opposite angles to the exterior angle will be equal to exterior angle.
