A parallelogram has two sets of perpendicular lines. The opposite sides of a parallelogram are parallel to each other, while the diagonals intersect at right angles if the parallelogram is a rectangle or a square. However, in a general parallelogram, the angles are not necessarily right angles, but the two pairs of sides remain parallel.
Yes, if it is an equiangular or equiangular and equilateral parallelogram (rectangle or square).

A parallelogram has 2 pairs of parallel lines and in the form of a rectangle it has 2 pairs of parallel lines and 4 perpendicular lines that meet at each of its corners at right angles.
Ah, isn't that a lovely question? In a parallelogram, there are two pairs of opposite sides that are parallel, but none of the sides are perpendicular to each other. Perpendicular lines meet at a right angle, and in a parallelogram, the sides do not meet at right angles, they run parallel in a harmonious way. Just like nature, everything has its place and purpose in a parallelogram.
They are what makes it a rectangle. The rectangle is a special kind of parallelogram. The perpendicular lines cause it to be called a rectangle.
Yes, if it is an equiangular or equiangular and equilateral parallelogram (rectangle or square).
