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?

As we can see the greatest length is 8 cm in the given data.


So, we draw a line of 8 cm and mark the first point on 5 cm on the same line. Now the remaining portion is of 3 cm length.


Now name the line according to its length as AB = 5cm, so starting point will be A, point B will be at 5 cm and the endpoint is C as AC is 3cm.


As shown in the figure (given figure is a rough diagram)

Now if we look closer we can see that AB and BC together form the complete line AC.


Point B lies between A and C.
