Web6 Sep 2024 · The triangle sum theorem states that the sum of the three interior angles in a triangle adds up to 180°. It is also called the angle sum theorem. Given below is a triangle … Web10 Apr 2024 · From the angle sum property of triangles we can infer that ∠ B A C + ∠ A B C + ∠ B C A = 180 ∘ or ∠ A B C = 180 ∘ − ( ∠ B A C + ∠ B C A). Therefore: ∠ A B C = 180 ∘ − ∠ C B D = 180 ∘ − ( ∠ B A C + ∠ B C A) ⇒ − ∠ C B D = − ( ∠ B A C + ∠ B C A) ⇒ − ∠ C B D × − 1 = − ( ∠ B A C + ∠ B C A) × − 1 ⇒ ∠ C B D = ∠ B A C + ∠ B C A Share Cite
