Prove that sum of angles of triangle is 180°

Webb10 juli 2024 · The equation to find the sum of interior angles is n-2(180) which means that a polygons interior angles will always be a multiple of 180 because they are multiplied by it. How will you prove that the sum of the interior angles of a triangle is 180? So, the angle sum ∠A + ∠B + ∠C is equal to the angle sum ∠A’ + ∠B’ + ∠C’. WebbA triangle’s internal angles add up to 180°, leaving 90° shared between the two equal angles when the right-angle is subtracted.. And 90° ÷ 2 = 45, every time. If Side 1 was not the same length as Side 2, then the angles would have to be different, and it wouldn’t be a 45 45 90 triangle!

Webb4 juni 2014 · Expert Answer Let x, y and z be the exterior angles of a triangle. Then the corresponding interior angles are: 180o - x, 180o - y, 180o - z. Since the sum of interior angles is 180o, therefore 180o - x + 180o - y + 180o - z = 180o Or, 540o - (x + y + z) = 180o Or, x + y + z = 540o - 180o = 360o. Hence the sum of exterior angles is 360o.
