Answer: A and B both are correct statements.


Step-by-step explanation:

Let ABCD is a parallelogram then its properties are as follows:-

1. Opposite angles and sides of parallelogram are always congruent.

i.e.AB=CD and AD=BC and ∠A=∠C and ∠B=∠D

2.Consecutive angles are supplementary.

i.e. ∠A+∠B=180° and ∠B+∠C=180°

3. Its diagonals bisect each other.

4. The sum of all the angles is 360°.
