Directrix (directrix):

As @KamiBug said, this problem has to do with the Triangle Inequality Theorem. One side of a triangle is shorter than the other two but greater than the positive difference of those other two sides.

Directrix (directrix):

@Adam96 The third side will be less that ? (according to theorem?)

Directrix (directrix):

Directrix (directrix):
