Question

If AB = 8 units and M is the midpoint of AB, then AM = ________ units.

• A. 4
• B. 2
• C. 8
• D. 10

Answer 1

The correct option is A 4


Let M be the midpoint of a line segment with length 8 units. Midpoint M divides the line segment into two equal parts AM and BM.
$\therefore AB=AM+BM=8$
$\therefore AM=\frac{8}{2}=4$ units
