Where side refers to the length of any one side.Īs for the angles, a regular hexagon requires that all angles are equal and sum up to 720º, which means that each individual angle must be 120º. These restrictions mean that, for a regular hexagon, calculating the perimeter is so easy that you don't even need to use the perimeter of a polygon calculator if you know a bit of math. For the sides, any value is accepted as long as they are all the same. In a regular hexagon, however, all the hexagon sides and angles must have the same value.

The angles of an arbitrary hexagon can have any value, but they all must sum up to 720º (you can easily convert them to other units using our angle conversion calculator). In very much the same way an octagon is defined as having 8 angles, a hexagonal shape is technically defined as having 6 angles, which conversely means that (as you can see in the picture above) the hexagonal shape is always a 6-sided shape.
