. The lines `(a+b)x + (a-b) y-2ab=0, (a-b)x+(a+b)y-2ab = 0 and x+y=0` form an isosceles triangle whose vertical angle is

Two sides of a triangle are (a+b)x+(a-b)y-2ab=0 and (a-b)x+(a+b)y-2ab=0 .If the triangle is isosceles and the third side passes through point (b-a,a-b), then the equation of third side can be
