Let DEF be a rectangular triangle such that D=[0 0 0], E=[3 0 0] and F=[0 4 0]. On the sides DE, DF and EF are constructed respective halfcircles with positive zaxis and perpendicular to the xyplane. Determine the parameters A, B, C of the plane A*x + B*y + C*z = 1 , that tangents the three halfcircles.
