Length of diagonal of a tetragon of which two neighboring interior angles are right (90 degrees), as shown in figure, is calculated as below.

Letting the height as h, the Pythagorean theorem leads to;
h = (b^2 - (c-a)^2)^(1/2)

Then, the diagonal length L is :

L = ( h^2 + c^2 )^(1/2) = ( (b^2 - (c-a)^2) + c^2 )^(1/2)
= ( -a^2 + b^2 + 2*a*c)^(1/2)


*** Âü°í¹®Çå[References] ***

L = ( -a^2 + b^2 + 2*a*c)^(1/2)
