Segment Addition Postulate States that, if there are three Points A, B and C , such that, point C lies between A and B, then
This Postulate states that
AC + BC=AB
Real World Object(Model)
Consider a wooden block , located at the base of floor and it touches the ceiling of roof .At a point a Nail is thrashed inside it, at a distance of 40 cm from the base.And Height of the nail from ceiling is 60 cm.The total height of Wooden Block is 100 cm.Proof Segment addition postulate for this Problem.
Proof:
Total Height of wooden Block=100 cm(PQ)
Height of nail from base =40 cm(PR)
Height of nail from Ceiling= 60 cm(QR)
⇒100=40+60
⇒PR+QR=PQ
