Answer 1

its true

Irregular pentagons can be a convex pentagon or a concave pentagon, but they must have five different-length sides. A common example of a convex irregular pentagon is the home plate on a baseball field. All pentagons (regular and irregular) are five-sided shapes, with five interior angles and five exterior angles.
