**A regular hexagon looks like a rectangle that has a triangle attached to the top and the bottom of it.** An irregular hexagon can have any shape as long as it has six sides.

A hexagon is defined as a polygon that always has six sides. It is always flat, but the length of the sides can vary. A hexagon that has six equal sides and six equal angles is known as a regular hexagon. The interior angles of a regular hexagon are 120 degrees, while the exterior angles are always 60 degrees. Hexagons that have unequal angles and sides of varying lengths are known as irregular hexagons.
