Does a parallelogram have one pair of opposite parallel sides? No. If only a pair of opposite sides is parallel, then it forms a trapezium and when two pairs are parallel, then it forms a parallelogram.
Narasimham
A square has four pairs of parallel lines. Each pair consists of two opposite sides that run parallel to each other, resulting in a total of two pairs for the horizontal sides and two pairs for the vertical sides. Thus, the total is four pairs of parallel lines.
