"Diagonals of parallelogram `A B C D`
intersect at `O`
as shown in Figure. XY contains `O ,\ a n d\ X ,\ Y`
are points on opposite sides of the parallelogram.

Give reasons for each of the following:
`O B=O D`
(ii) `/_O B Y=/_O D X`

`/_B O Y=\ /_D O X`


(iv) ` B O Y~= D O X`

Now, state if `X Y`
is

bisected at `Odot`"
