If the locus of the points which are equidistant from points P and Q meets line PQ at point N, then PN equals
Answer Details
The locus of the points which are equidistant from points P and Q is the perpendicular bisector of PQ. Let's call it line M.
Point N is where line M intersects with line PQ. Therefore, PN is the perpendicular distance from point N to line M.
Since M is the perpendicular bisector of PQ, PN is also the perpendicular distance from point N to line PQ.
Therefore, PN = NQ.
So, the correct option is "NQ".
