Question

plz solve the question n0.24

Answer 1

CD║AB, XY║$X^{'} Y^{'}$

∠CPO =90
∠AOP =90

AOPC is a square as all the angles are 90 and alternate sides and opposite angles are equal 

AO=CP=OP

PO=PC

O and C are equidistant from P

 so circle with centre as P will pass through D 

which means the circle with centre as P will pass through C and D
