If two parallel lines are cut by a transversal, then corresponding angles are

• supplementary

• congruent

• complementary

When two lines in a plane are cut by a transversal, and if corresponding angles are congruent, then the two lines are

• intersecting

• supplementary

• complementary

• parallel

In the figure, the angles labeled 1, 2, 7, and 8 are

• congruent angles

• interior angles
