Given a collection of points P in a plane and a point Q in another plain,
which is equidistant from all point in P, which of the following are necessarily true?

A. The points in P lie on a circle.

B. If all these points are met to each other by line segments, all segments will be on outer surface of an imaginary right circular cone.

A and B
Neither A nor B
B only
A only

• Ans is: A and B.
  Since the point Q in other plane is equidistant from all the points in P, thus it is clear that the points P are arranged in circular manner.....and if we connect these points with Q it is certainly going to form a right circular cone with its vertex at Q.

• A only.
  
  Because
  If all these points are met to each other by line segments, the line segments joining points P in a plane will lie inside the imaginary cone.
