O is a point in the interior of triangle ABC. Use the symbols( =) to make the following statements true.
A. OA+OB. ... .......AB
b. OA+OC ............AC
c.OB +OC. ............BC
now,show that AB+AC+AB
Answer :
We form our diagram from given information , As :
We know from the triangle inequality theorem that any side of a triangle is always shorter than the sum of the other two sides.
So,
A ) OA + OB > AB ( Ans )
B ) OA + OC > AC ( Ans )
B ) OB + OC > BC ( Ans )
Now we add all thee equation and get
OA + OB + OA + OC + OB + OC > AB + AC + BC
2 ( OA + OB + OC ) > AB + AC + BC ( Ans )
