Each interior angle is 120 deg, and all interior angles together sum to 720 deg.
A Hexagon has 9 diagonals, computed as n(n-3)/2.
The circumradius is 1.1547 times the inradius. As n grows larger, this ratio approaches 1 and the polygon approaches a circle.
Next stepAll outputs assume a regular (equilateral and equiangular) polygon. For irregular polygons, use the Shoelace formula with known vertex coordinates.
