Dodecagon Calculator
Calculations at a regular dodecagon, a polygon with 12 vertices. Enter one value and choose the number of decimal places. Then click Calculate.
Formulas:
d6 = ( √6 + √2 ) * a
d5 = ( 2 + √3 ) * a
d4 = ( 3*√2 + √6 ) / 2 * a
d3 = ( √3 + 1 ) * a
d2 = ( √6 + √2 ) / 2 * a = d6 / 2
Height = d5
p = 12 * a
A = 3 * ( 2 + √3 ) * a²
rc = d6 / 2 = d2
ri = d5 / 2
Angle: 150°
54 diagonals
Edge length, diagonals, height, perimeter and radius have the same unit (e.g. meter), the area has this unit squared (e.g. square meter).
