How to Calculate Inner side of Concave Quadrilateral?
Inner side of Concave Quadrilateral calculator uses side_d = sqrt(Side A^2+Diagonal^2-(2*Side A*Diagonal)*cos(Angle B)) to calculate the Side D, Inner side of Concave Quadrilateral formula is defined as
d = √ a² + f² - 2af * cos( β2 ) where a is outer side, f is diagonal and β2=β - β1 of concave quadrilateral. Side D and is denoted by S_{d} symbol.
