Q1 · Difficulty 1/3
A student constructs the perpendicular bisector of line segment PQ. Any point on this line is equidistant from which two points?
- P and the midpoint of PQ
- P and Q
- Q and the origin
- The midpoint of PQ and the origin
Show answer & explanation
✓ Answer: B — P and Q
Every point on the perpendicular bisector of PQ is exactly equidistant from P and Q — this is the fundamental locus property of a perpendicular bisector. Option A is incorrect as equidistance is between P and Q, not involving the origin. Option C is wrong because equidistance is from both endpoints P and Q, not P and the midpoint. Option D incorrectly introduces the origin.
