Answer Text:
Perpendicular bisector locus.
The locus of a point which are equidistant from two fixed points is the perpendicular bisector of the straight line joining the two fixed points. This locus is called the perpendicular bisector locus. So to find the point equidistant from two fixed points you simply find the perpendicular bisector of the two point Q is the mid-point of M and N. In three Dimensions In three dimensions, the perpendicular bisector locus is a plane at right angles to the line and bisecting the line into two equal parts. The point P can lie anywhere in the line provided its in the middle.
