Answer: We can only conclude that OA=OB=PD=DE.
Explanation:
Since, if two circle are congruent then there radius must be equal.
And, here A and B are the points in the circumference of circle O therefore, the distance of these points from the center O of circle is the radius of the circle.
So, OA=OB. ( if we join the points O and C then OA=OB=OC)
Similarly, In Circle P, PE= PD. ( if we join the points P and CF then PD=PE=PF).
