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. 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.
In a parallelogram, there are two pairs of opposite sides that are parallel to each other. Since parallel lines do not intersect, there are no perpendicular lines within the parallelogram itself. However, if you consider the diagonals of a parallelogram, they are perpendicular to each other, intersecting at right angles. Therefore, there are two perpendicular lines in a parallelogram when you consider its diagonals.
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.
