Properties. A regular hexagon has: Interior Angles of 120° Exterior Angles of 60° Area = (1.5√3) × s 2, or approximately 2.5980762 × s 2 (where s=side length) AND there is a huge hexagon on Saturn, it is wider than Earth. read more
An irregular polygon is any polygon that is not a regular polygon. It can have sides of any length and each interior angle can be any measure. They can be convex or concave, but all concave polygons are irregular since the interior angles cannot all be the same. read more
Any other polygon is an irregular polygon, which by definition has unequal length sides and unequal angles between sides. Circles and shapes that include curves are not polygons - a polygon, by definition, is made up of straight lines. read more
