Angle 1 = 90 nahi hai
ON divides CD
But, thanks for your help
To first angles = 90 hi hoga
when a line from centre bisect the chord it forms 90°
First draw OP parallel to CD and AB as shown in the figure. Then angle NOP = angle ONC similarly angle POM would be equal to angle OMA but the sum of former angles is 180 degrees therefore the latters will also sum up to give 180 degrees and hence the line ONM is a straight line.
It was assumed that O was the centre
Thank you
O ko centre assume Kar ke hi batayein hain
Okk
