Given points A B C with AB = 3 cm AC = 4 cm BC = 5 cm Can point A lie on the segment BC?

If point A lay on the segment BC, that is, it was between points B and C, then AB + AC should be equal to BC.

AB + AC = 3 cm + 4 cm = 7 cm.

7 cm does not equal 5 cm.

Thus, we can make an easy conclusion that point A cannot lie on the segment BC.
