A pentagon can be either irregular or regular, depending on its characteristics. A regular pentagon has equal sides and equal angles, while an irregular pentagon has sides and angles of varying lengths and measurements. In summary, a pentagon's classification as regular or irregular is determined by the uniformity of its sides and angles.

A pentagon is a five sided figure. If the five sides are all the same length, then the pentagon is a regular pentagon; if they are not all the same length, then it is an irregular pentagon.

Only partially correct. In addition to equal sides, a regular polygon must also have equal angles.
No. A pentagon is a polygon. It may or may not be regular.
A regular pentagon has all its sides of equal length and all its angles equal. An irregular pentagon does not. Several other differences follow from this distinction.
It depends! If all its sides and angles are the same then it is a regular pentagon, however, if it's a five sided shape (5 straight sides that join to make a single shape), but it's sides or angles are not equal then it is an irregular pentagon.
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 does not have any perpendicular sides. A pentagon is made up of five sides. An irregular pentagon which has sides that are not equal may have a perpendicular side.
