We join C and D,
and A and B.
Now we get Triangle DOC and Triangle AOB,
In these two Triangles we get the following points,
1), OD=OA ( given),
2), OC=OB,( given),
3), Angle DOC=Angle AOB= 90°
Therefore
Triangle DOC congruent to Triangle AOB, Here SAS congruency occurred,
Therefore AB=CD,
Hence proved.
