Answer 2

If both pairs of opposite sides of a quadrilateral are congruent, then it’s a parallelogram (converse of a property).

Tip: To get a feel for why this proof method works, take two toothpicks and two pens or pencils of the same length and put them all together tip-to-tip; create a closed figure, with the toothpicks opposite each other. The only shape you can make is a parallelogram.
