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 perpendicular lines are on a parallelogram?

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.

How many sets of perpendicular lines does a parallelogram have?

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.
