Congruent Triangles / 153 A perpendicular bisector of a segment is a line (or ray or segment) that is perpendicular to the segment at its midpoint. In the figure at the right, line l is a perpendicular bisector of JK. In a given plane, there is exactly one line perpendicular to a segment at its midpoint. We speak of the perpendicular bisector of a segment in such a case. Proofs of the following theorems are left as Exercises 14 and 15.
