WebJun 4, 2014 · In an equilateral triangle ABC, D is a point on side BC such that BC. Prove that 9AD2 = 7AB2. Asked by Topperlearning User 04 Jun, 2014, 01:23: PM Expert Answer Draw AP BC. BD = Since ABC is equilateral and AP BC, BP = PC = BC = AB Using Pythagoras theorem in ABP, AP2 + BP2 = AB2 AP2 = AB2 - BP2 = AB2 - = … (1) WebWe know that BD is the angle bisector of angle ABC which means angle ABD = angle CBD. Now, CF is parallel to AB and the transversal is BF. So we get angle ABF = angle BFC ( alternate interior angles are equal). But we already know angle ABD i.e. same as angle ABF = angle CBD which means angle BFC = angle CBD.
