Question

if A,B and C are 3 points on a line and B lies b/w A and C , prove that AB +BC= AC ( EUCLIDS GEOMETRY)

Answer 1

Ac coincide with AB+BC.
Also, Euclids Axiom (4)sayes that things which coincide with one another are equal to one another. So, it can be deduced that
AB+BC=AC
Note that in this solution, it has been assumed that is a unique line passing through tow points
