    Triangle inscribed in one Circle

    Let c be the circumscribed circle of triangle ABC and let P be the point on c where the bisector of angle ABC meets c. Let O be the center of c. Prove that the radius of segment OP meets segment AC at right angles.

    Any help with this proof would be greatly appreciated....
