Question

Consider the diagram.

Line l is a perpendicular bisector of line segment A C. It intersects line segment A C at point B. Line l also contains point D. The length of line segment A D is 16. The length of line segment B C is 9.
What is the length of segment AB?

7
9
18
25

Answer 1

9

Explanation:

just took the test

Answer 2

AB = 9

Explanation:

Given that line, l is a perpendicular bisector of line segment AC. It intersects line segment AC at point B.

So, we can conclude that AB = BC ............ (1)

Also given that the length of line segment BC is 9.

Now, from equation (1) we can say that, AB = 9.

Therefore, the length of segment AB is 9. (Answer)
