2. Adjacent angles are two coplanar angles with a common side, a common vertex, and no common interior points. Vertical angles are two angles whose sides are opposite rays. Complementary angles are two angles whose measures have a sum of 90. Supplementary angles are two angles whose measures have a sum of 180.

3.  5 and  4 are supplementary angles.  1 and  4 are vertical angles.  4 and  3 are complementary.

4.  1 and  2 are _____________________  6 and  5 are _____________________  6 and  2 are _____________________

6. If two angles form a linear pair, then they are supplementary.
