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

• d is the ans bcoz lines connecting points are chords nd chords can be smaller than radius also..............

• d above condition is satisfied if all d points lie on a circle..
  so ans is a.

• A only...
  all points have to be equidistant ie the radius of the circle on which the points lie..
