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)A only
  Soln: all points in a circle are equidistant from a given point.

• d) A only .

• A only.. B is not possible because line joining any two points in P becomes a chord which is always less than the radius(line joining X and any point in P) of circle..

• A only.

• ans ia A .
• 11 years agoHelpfull: Yes(1) No(8)
• D) A only as all points are equidistant from a given point
• 8 years agoHelpfull: Yes(0) No(0)
• d . because for being all points equidistant point p should be its center but statement B doesnot need to be necesarily true..

• a only. because the chord may be greater or lesser than the radius.

• the correct answer is neither A nor B
