For the given figure, find the relation between the chords, AB and CD.
AB=a.CD
AB=CD
AB=1aCD
AB=2CD
The chords, AB and CD are at a distance of a units from the centre.
We know that equal chords are equidistant from the centre.
Hence, AB=CD
In the given diagram, O is the centre of the circle and chord AB = chord BC. (i) What is the relation between arc AB and arc BC? (ii) What is the relation between ∠AOB and ∠BOC? [1 Mark]
