Answer 2

Answer:

plese mark me as the brainliest

Step-by-step explanation:

By proving a pair of parallel sides in a parallelogram we can prove another pair of sides as parallel or equal sides because we know that the distance/length between two parallel side is equal.

Now we have proved a pair of opposite sides parallel and two pair of opposite sides equal.

we know that in a parallelogram opposite sides are equal .
