Quadrilateral Calculator

Calculations in a general, convex quadrilateral or quadrangle. The calculation is done by fragmenting the quadrilateral into triangles, which can be calculated with the according formulas. Enter the first three lengths a, b and c and the two angles between them, β and γ. Please enter angles in degrees, here you can convert angle units.


Euclid Side a: Quadrilateral
Side b:
Side c:
Side d:
Angle α:
Angle β:
Angle γ:
Angle δ:
Diagonal e:
Diagonal f:
Perimeter (p):
Area (A):
Round to    decimal places.



Quadrilateral shape (a bottom, b right, c top, d left). If this quadrilateral is drawn non-convex, that is if it has an indent or is crossed, the upper calculation is not valid:
Formulas:
e = √ a² + b² - 2ab * cos( β )
f = √ b² + c² - 2bc * cos( γ )

γ1 = arccos( (b² + e² - a²) / 2be )
γ2 = γ - γ1
d = √ c² + e² - 2ce * cos( γ2 )

α = arccos( (a² + d² - f²) / 2ad )
δ = 360° - α - β - γ
p = a + b + c + d
A = √ 4e²f² - ( b² + d² - a² - c² )² / 4

Side length, diagonals and perimeter have the same unit (e.g. meter), the area has this unit squared (e.g. square meter), the angles are in degrees.
