Question

What 9s the exterior angle property of a triangle

Answer 1

Answer:

Properties. An exterior angle of a triangle is equal to the sum of the opposite interior angles. ... If the equivalent angle is taken at each vertex, the exterior angles always add to 360° In fact, this is true for any convex polygon, not just triangles. See Exterior angles of a polygon.

What is the exterior angle property of a triangle ?

${\underline{\underline{\huge{\red{\bold{Answer}}}}}}$

The angle formed by a side with its extended adjacent side of a triangle is called an exterior angle of the triangle.

Exterior angle property states that the measure of exterior angles of a triangle is equal to the sum of its two interior opposite angles.

Here, ∠ACD is the exterior angle of the ΔABC. This angle is formed with the side AC and extending the side BC of the triangle.

∴∠ACD = ∠A + ∠B

 Exterior angle property holds for all triangles.
