== == yes. suppose the quad ABCD has AB and CD equal and parallel. Then the triangles ABC and CDA are congruent by SAS axiom; so the quad is a parallelogram
The key is the object is quadrilateral with parallel sides. It is a parallelogram. It is also a rhombus.
A parallelogram has two pairs of congruent sides.
It is a rhombus or a parallelogram
No, it doesn't have to be. A quadrilateral can definitely be a parallelogram only if: - Both pairs of opposite sides are parallel. - Both pairs of opposite sides are congruent. - One pair of opposite sides are both congruent and parallel. - Both pairs of opposite angles are congruent. - The diagonals bisect each other.

The Opposite Sides Parallel and Congruent Theorem states that if a quadrilateral has a pair of opposite sides that are parallel and congruent, then the quadrilateral is a parallelogram.
No. The congruent sides need not be parallel.
A parallelogram.
true

Then, the opposite sides are congruent.
False
