Identify the diameter in the given figure.
Radius-OA ; Chord-BC ; Diameter AB ; Centre-O
Radius-OA,OC,OB ; Chord-BC ; Diameter AB ; Centre-O
Radius-AC ; Chord- OA,OB,OC ; Diameter AB ; Centre-O
Radius-OA,OC ; Chord-BC ; Diameter AB ; Centre-O
Diameter is a line segment with two ends on the circle and passing through its centre.
. O is any point in the interior of a triangle ABC. Prove that
1. AB + AC > OB + OC
2.AB + BC + CA > OA + OB + OC
3.OA + OB + OC > 1/2(AB + AC + BC)
