What are the inferences that you can get from the given figure?
The locus is the line PQ, which is the ⊥of MN.
The point 'O' is equidistant from M and N.
The observations we can get from the given figure are:-
-The locus is the line PQ, which is the ⊥of MN.
-The locus of a point equidistant from two fixed points is the ⊥ of the line joining the two fixed points.
-Any point on the ⊥ of a straight line joining the two given points say M and N is equidistant from these points.
