Complete the missing parts of the paragraph proof.
We know that angle 1 is congruent to angle 3 and that
line I is parallel to line m because
We see that
is congruent to
by the alternate
interior angles theorem. Therefore, angle 1 is
congruent to angle 2 by the transitive property. So, we
can conclude that lines p and q are parallel by the
