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.
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.
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.

How many altitudes equal in the parallelogram?
The single altitude of a parallelogram is its perpendicular height
How many perpendicular lines are there in a trapezium?
A trapezium has no right angles therefore there are no perpendicular lines. If it had perpendicular lines, it would be a square or rectangle.
How many perpendicular lines in a triangular prism?
9 perpendicular lines
How many perpendicular lines does a five point star have?
A Star has 0 perpendicular lines!
Can the diagonals of a parallelogram be perpendicular?
Yes, if the parallelogram is a rhombus or a square.
How many perpendicular lines does an octagon have?
There can be up to 8 perpendicular lines.
If a parallelogram is a rhombus then its diagonals are?
A parallelogram is a rhombus if and only if the diagonals are perpendicular
Does a parallelogram have perpendicular sides?
A parallelogram doesn't necessarily have any perpendicular sides, but it can. If it has one single 90-degree angle, then it has four of them, and it's a rectangle or square. A parallelogram without perpendicular sides is a rhomboid or rhombus.
