**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.

**Example of Segment Bisector**

- In the given figure, the line segment DE is the bisector of the segment AC as it intersects the line segment AC at its midpoint B.

**Solved Example on Segment Bisector**

What is the length of AB, if line

lis the segment bisector and AO = 6 units?

Choices:

A. 13 units

B. 6 units

C. 12 units

D. 14 units

Correct Answer: C

Solution:

Step 1:Lineldivides 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.
