Figure shows a circle of radius R . Let AB and CD are chords that is passing through a point E .
Chord AB is bisected at E . Chord CD is not bisected at E.
Perpendicular distance h1 to the chord AB is greater than perpendicular distance h2 to the chord CD .
Length of chord AB
Length of chord CD
Since h1 > h2 , we get AB < CD
Hence , if many chords are passing through a common point within a circle ,
then length of chord that is bisected by the common point has smallest length
