Definition of Segment Bisector
A Segment Bisector is a line or a ray or a segment that divides a line segment into two equal parts.
More About Segment Bisector
- A segment bisector always passes through the midpoint of a line segment.
- If a segment bisector crosses the segment at 900, then it is called as perpendicular bisector of the segment

Solved Example on Segment Bisector
Ques: What is the length of AB, if line l is the segment bisector and AO = 6 units?
A. 13 units
B. 6 units
C. 12 units
D. 14 units
Correct Answer: C
Step 1: Line l divides AB into two equal parts and O is the midpoint of AB.
[As the segment bisector passes through the midpoint of the segment.]
Step 2: AB = 2(AO) = 2(6) = 12 [Substitute AO = 6.]
Step 3: So, the length of AB is 12 units.
