To prove:straight line MN passes through Centre O.
Construction: through the Centre O draw EF parallel AB parallel CD
Join OM and ON
Proof :OM PERPENDICULAR AB
M Is mid point of AB and line joining Centre to midpoint of chord.
AngleOMA=90
AmgleMOF=90(OF parallel AB)
ON perpendicular CD
ON is the line joining the center of the circle to the midpoint of chord.
AngleONC=90
AngleNOF=90
Angle NOF +angleMOF=90+90=180
MON is straight line

Brother you are almost correct but you wrote perpendicular bisectors of the chords pass through the centre but that thing has to be proved according to the question
ok
pls do accordingly
do you know how to edit
