Question

If A, B, C are three points on a line such that AB = 5 cm, BC = 3 cm and AC = 8 cm, which one of them lies between the other two?

Answer 1

$\overline{AC}$ is the longest line segment as it is 8cm. Also AB + BC = 3 + 5 = 8cm = AC. So it is evident that points A,B and C are co-linear.
Therefore, B is the point between A and C.
