Answer:
So, AC || BD
We know, rangers is perpendicular to the radius at the point of contact.
So, angle OAC = angle OBD = 90
in quadrilateral ACDB,
AB|| CD
AC || BD
Angle BAC= 90
Hence, it is clear that Quadrilateral ACDB is a rectangle
So, angle C = angle D = 90
Now in quadrilateral OACP,
Angle A = 90
Angle C =90
Angle OPC = 90 and angle AOP = 90
This implies quadrilateral OACP is a rectangle.
So, OA = PC [ we know opposite sides are equal of rectangle]
similarly, quadrilateral OBDP is a rectangle
This implies OB = PD
Also OA = OB = OP [ theses are the radii of the same circles ]
So, PC = PD = OP
This implies , points O, C and D are equidistant from point ap
Hence, A circle with centre P and radius OP will pass through C and D
