WebProve that in a triangle A B C, ∠ A = ∠ 2 B, if and only if: a 2 = b ( b + c) where a, b, c are the sides opposite to A, B, C respectively. I attacked the problem using the Law of Sines, and tried to prove that if ∠ A was indeed equal to 2 ∠ B then the above equation would hold true. Then we can prove the converse of this to complete the proof. WebUses the law of cosines to calculate unknown angles or sides of a triangle. In order to calculate the unknown values you must enter 3 known values. To calculate any angle, A, B or C, enter 3 side lengths a, b and c.
