Homework Help: Similarity of triangle

  1. Jul 17, 2010 #1
    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?

    No worries. It's nice to see you actually know how to do this question, you have no idea how many high school students (even in year 12) getting nowhere in this kind of geometry.
