Step-by-step explanation:

construction:

join AD and BC

To prove: AP × PB = CP × PD

Proof :

In triangle APD and triangle BPC

angle PAD = angle PCB. { angle in the same segment...}.

similarly, angle ADP = PBC

Triangle APD ~ triangle BPC { by AA postulate }

AP/CP = PD/PB { corresponding sides of similar triangles }

= AP × PB = CP × PD

proved...
