None
It depends on the pentagon. If it is regular, then there are no parallel sides.
5 sides and it is a regular pentagon
How many pairs of perpendicular sides does this figure have?
A single side cannot be perpendicular on its own. Two sides are perpendicular if they intersect at a 90 degree angle. There are many polygons, both regular and irregular, that can have perpendicular sides.
None normally in a regular 5 sided pentagon but it is possible to construct an irregular pentagon with a pair of parallel sides.
A regular pentagon has zero perpendicular sides. If it is irregular, it could have as many as 2 or 4 perpendicular sides.
A regular 5 sided pentagon has no perpendicular lines
5
a regular pentagon has five sides. The word regular means equal
If the question refers to sides than a regular pentagon has 5 sides.
