1. The problem statement, all variables and given/known data At ΔPQR, a line is drawn parallel to QR, cuts PQ at S and PR at T. Line SR and QT intersect at X. Show that PS / PQ = TX / XR 2. Relevant equations 3. The attempt at a solution I can not achieve that proof. The best I can get is : PS / PQ = TX / XQ. Something wrong with me or the question?
