What is the difference between a perpendicular and a perpendicular bisector?

Lines which intersect to form a right angle (90°) are known as perpendicular lines.

Example:

In the given figure, AB is perpendicular to CD. ∠AOC = ∠AOD = ∠BOD = ∠BOC = 90°.

A line *p* is said to be perpendicular bisector of another line segment AB, if *p* is perpendicular to AB and *p *bisects AB.

In the given figure, *p* ⊥ AB and *p* intersects AB in O such that OA = OB.
