Given a parallelogram ABCD. Complete each statement along with the definition or property used. (i) AD = __________ (ii) ∠DCB = __________ (iii) OC = __________ (iv) m∠DAB + m∠cda=__________

(i) AD = BC [Since opposite sides of a parallelogram are equal]
(ii) ∠DCB = ∠DAB [Since opposite angles of a parallelogram are equal]
(iii) OC = OA [Since diagonals of a parallelogram bisect each other]
(iv) m ∠DAB+m∠CDA = 180°
[Adjacent angles in a parallelogram are supplementary]
