Question

What is a perpendicular bisector?

Answer 1

The perpendicular bisector of a line segment:

A perpendicular bisector can be defined as a line segment that intersects another line perpendicularly and divides it into two equal parts as any bisector divides a line segment into two equal parts.

In the below diagram, $XY$ is the perpendicular bisector of the line segment $PQ$.

So that, $JP=JQ$

Hence, the perpendicular bisector is a line segment that intersects another line perpendicularly and divides it into two equal parts.
