Question

# Find the length of the segment AB

- 9
- 6
- 12
- 15

Hint:

### If a line is drawn parallel to any one side of a triangle so that it intersects the other two sides in two distinct points, then the other two sides of the triangle are divided in the same ratio.

## The correct answer is: 9

Hence, the correct option is B.

It is also called basic proportionality theorem or Thales' theorem.
