Question

in figure PQ=XY, OM=4cm, find the length of ON​

Answer 1

Solution : In the figure O is the centre of the circle and OM,ON are the perpendiculars from the centre to the chords PQ and RS respectively.

If OM=ON and PQ=6cm

We know that if two chords are equidistant from the centre then the two chords are equal in length.

Hence PQ=RS

∴RS=6cm
