### Solved Example on Segment Bisector

**Ques: **What is the length of AB, if line l is 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: 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.
