How Many Degrees Are in a Hexagon?

The sum of all the interior angles in a hexagon is equal to 720 degrees. A hexagon is a polygon that consists of six straight line segments and six interior angles. However, there are regular and irregular hexagons.


If a hexagon has six equal side lengths and six angles that are also equal, then it is a regular hexagon. All other hexagonal-shaped polygons that do not conform to this definition are irregular hexagons.

Hexagons can be either convex or concave polygons. While a convex hexagon has all interior angles that are less than 180 degrees, a concave hexagon can have one or more interior angles that are greater than 180 degrees. Convex hexagons also have vertices that point outward, and concave hexagons can have at least one vertex that points inward.
