Given a collection of 36 points P in the plane and a point equidistant from all points in P, which of the following are necessarily true?
A. The points in P lie on a circle.
B. The distance between any pair of points in P is larger than the distance between X and a point in P
a) A and B
b) Neither A nor B
c) B only
d) A only

• Ans is A)The points in P lie on a circle
  that is 35 points is lie on circle and 36th point is lie in the mid of the circle,then only all the points equidistant from all points
