A triangle defined by three lines

How to use the calculator

Enter the coefficients A, B and C involved in the equations of the lines defined by:

A x + B y + C = 0

and press "enter". The output is the area. In case the three lines do not form a triangle, for example if two of them are parallel, then the area is "undefined".
