whole theorem might be lengthly dear but i can give u d procedure....we 'll take general case....
eqn to PP'=>x=b/a sintheta
and DD'=>x=b/a cosec theta.......
now u can find d points P,P',D,D'........
prove that mid points of P'D' nPD lie onfirst asympote........i.e y=bx/a
n similarly for d other:)
