Answer:

Hence proved, in triangle ABC, ∠B + ∠A + ∠C = 180°. Thus, the sum of all the angles of a triangle is equal to 180°. The sum of the angles of a triangle is always 180°. If any side of a triangle is extended, then the exterior angle thus formed is equal to the sum of the two interior opposite angles.
