    Since all six lines are parallel, then all the pairs of alternate interior angles are congruent. To be classified by this term, the angles have to be formed using the same transversal cutting through parallel lines.

    9&4, 3&10, 11&18, 12&17 etc on the left side

    7&14, 13&8, 15&20, 16&19 etc on the right side.

    There cannot be any non-congruent alternate interior angles using the same transversal.
