    Inscribed triangle problem

    I need help with the following problem.

    Triangle ABC is inscribed in a circle. From a point P on the circumference 3 lines are drawn perpendicularly to the three triangle sides intersecting them at points R, S and T.

    Prove that R, S and T are collinear.

    Thank you in advance.
