Why does a light ray incident on a rectangular glass slab immersed in anyu medium emerge parallel to itself?

The light day incident on glass slab gets refracted when in travels from air (lighter medium ) to glass (denser medium) then back again to air.
The light is incident and emerges to the same medium i.e air so the ray bends in such a way that the i = r and since the angles are equal the lines are parallel.
