WebProof of Angle bisector theorem. We can easily prove the angle bisector theorem, by using trigonometry here. In triangles ABD and ACD (in the above figure) using the law of sines, we can write; A B B D = s i n ∠ B D A s i n ∠ B A D …. ( 1) A C D C = s i n ∠ A D C s i n ∠ D A C …. WebAnswer (1 of 5): Applying cosine rule on \angle BDA, we get: c^2 = q^2 + p^2 - 2pq\cos{45^o} Applying sine rule on \triangle BDA, we get: \dfrac{c}{\sin{45^o ... interoperability phase 2
