4. Two lines intersect to form \( \angle A B C \). One step in constructing a line parallel to \( B C \) through point \( A \) is to construct an angle congruent to \( \angle A B C \) with vertex \( A \). Which theorem can you use to prove that the line you constructed is parallel to the given line?
