A parallelogram has four sides, but it typically does not have any perpendicular lines. The opposite sides are parallel, and the angles are not right angles unless it is a special case of a parallelogram, such as a rectangle or square. In those cases, the adjacent sides would be perpendicular, resulting in four right angles. Thus, in a general parallelogram, there are no perpendicular lines.

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.
A parallelogram has two sets of perpendicular lines.

However, in a general parallelogram, the angles are not necessarily right angles, but the two pairs of sides remain parallel.
It may have either none, or four. If the angles are ninety degrees, then we have a rectangle, which is a special case of a parallelogram, and each side is perpendicular to the next. For any other set of angles, no sides are perpendicular.
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.
