Answer:
Following are the proving to this question:
Step-by-step explanation:
Please find the graph image in the attachment.
Given O is the mid-point of AB and CD
[tex]\to OA=OB \\\\\to OC=OD\\\\In\ \Delta AOD,\Delta BOC\\\\AO=BO\\\\ CO=DO\\\\ \angle AOD= \angle BOC (\text{vertically opposite angles}) \\\\[/tex]
[tex]By \ S.A.S \ congruency \\\\\Delta AOD \cong \Delta BOC \\\\\to AD=BC[/tex]
