I'm trying to draw a triangle - a right angled triangle where I know the length of the hypotenuse (h) and one other side(x), but not the length of the other side, nor the other 2 angles.

The equation, as I'm sure we all know, is h^2 = SQRT(x^2 + y^2)

Obviously I can resolve y manually (well with a calculator since in my case the numbers were horrible), but I'm thinking that's exactly the sort of calculation QCad should be doing for me. Is there a way?
