In the previous question asked by me PQRS is a parallelogram. QA bisects angle pqr and meet PS at A. A straight line through R and parallel to QA meets PQ produced at B and PS produced at C. Prove that traingle PBC is an isosceles triangle. The solution provided by topperlearning experts is totally wrong. The question is asking something and the answer provided is telling different thing. Infact the solution provided by your experts is wrong. I have my exam today and I posted that question yesterday. I thought that I will get the correct answer for it. But I couldn't get that. Sorry to say, but my trust over topperlearning experts has been lifted.
