In triangle PQR; QR = p, PR = q and PQ = r with Angle QPR = 2* Angle PQR. The length of all the three sides of the triangle are different.

Is it always true that: p² = q (q + r)?.

(In reply to Solution by Bractals)

The problem states that all sides are of different length. Therefore no need to consider the case of  q = r.
