Question

If AB = 4, find AC. B is the midpoint of AC

Answer 1

By definition, a midpoint divides a line or a segment into two equal parts.

If B is the midpoint of AC and AB = 4, then BC = 4 as well.

To get the length of AC, simply add the length of AB and BC.

`4+4=8`

Therefore, the measure of AC is 8 units.
