Question

If A,B,C are three points on line and B lies between A and C,then prove that AB+BC =AC.

Answer 1

since complete line is AC and B is point on it.
therefore, AC is divide into 2 parts AB&BC.
therefore, AC=AB+BC 

Answer 2

The given condition is A,B,C are three points on line and B lies between A and C.  

The following procedure is for proving that AB+BC =AC.

According to the given condition,

the complete line is AC and B is point on it.

Hence, AC is classified into two different parts  including AB and BC.  

And hence, AC=AB+BC.
