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

• exterior angles

• supplementary angles

Pairs of angles such as those labeled 1 and 5, or 4 and 8, are

• adjacent angles

• alternate interior angles

• corresponding angles

• complementary angles

The angles labeled 3 and 6 are

• alternate interior angles

• alternate exterior angles

• corresponding angles

• adjacent angles

If the  $m\angle1\ is\ 125\degree,\ then\ m\angle5\ is$  

•  $180\degree$  

•  $60\degree$  

•  $125\degree$  

•  $55\degree$
