Question

Show that a line segment has one and only one mid-point​

Answer 1

Answer:

let C and D be 2 mid points of line segment AB. since C is the mid point , AC=CB=1/2 AB similarily AD=BD=1/2 AB thus AC=AD AD+CD=AD therefore CD=0 units or C collides with D hence every line segment has one and only one playground

Answer 2

Answer:

let C and D be 2 mid points of line segment AB. ... suppose D is the another mid point of AB,AD=DB C is the midpoint of AB,Account=CB therefore AC-AD=CB-DB DC=-DC DC+DC=0 2DC=0 DC=0÷2 DC=0;therefore c and d are coincide. Thus every line segment has one and only one midpoint..
