Here r 1 = Δ s − a, r 2 = Δ s − b, r 3 = Δ s − c, r = Δ s I put these values and simplified r 1 + r 3 + r = r 2 to get c 2 sin 2 C 2 = b 2 cos 2 B 2 I am stuck here. Please help. trigonometry Share Cite Follow WebSo 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. Therefore triangle BCF is isosceles while triangle ABC is not.
