Hexagon Calculator

Side length (a)
Large diagonal (d1)
Smaller diagonal (d2)
Perimeter (p)
Square (S)
Radius of the inscribed circle (r)

Formulas:

d = 2 * a
d2 = √3 * a
p = 6 * a
S = 3/2 * √3 * a2
r = √3 / 2 * a
Height = d2 = 2 * r
Circle radius = a
Internal angles: 120°, 9 diagonals

S is the area, p is the perimeter
The sides and angles are equal to each other
Short diagonals form a hexogram
The long diagonals form six equilateral triangles, with the long edge a
Inscribed and circumscribed circle
