#### Question

Given a parallelogram ABCD. Complete each statement along with the definition or property used.

(1) AD = …

(2) ∠DCB = …

(3) OC = …

(4) *m*∠DAB +* m*∠CDA = …

#### Solution

1) In a parallelogram, opposite sides are equal in length.

AD = BC

2) In a parallelogram, opposite angles are equal in measure.

∠DCB = ∠DAB

3) In a parallelogram, diagonals bisect each other.

Hence, OC = OA

4) In a parallelogram, adjacent angles are supplementary to each other.

Hence, *m*∠DAB +* m*∠CDA =180°
