a. If two parallel lines are cut by a transversal, then the pairs of corresponding
angles are congruent.
b. If two parallel lines are cut by a transversal, then the pairs of alternate
interior angles are congruent.
c. If two parallel lines are cut by a transversal, then the pairs of alternate
exterior angles are congruent.
d. If two parallel lines are cut by a transversal, then the same-side interior
angles are supplementary.

See printed out notes I gave you on constructing parallel lines.
9.
Hypothesis (p): two lines are parallel
Conclusion (q): the corresponding angles are congruent
Converse: If corresponding angles are congruent, then two lines are parallel.
Inverse: If two lines are not parallel, then the corresponding angles are not
congruent.
Contrapositive: If the corresponding angles are not congruent, then two lines are
not parallel.
