4. Theorem 2.6: Vertical Angle Theorem:

5. Complementary angles are two angles whose measures have a sum of 90 degrees. Each angle is called a __________ of the other. complement

6. Supplementary angles are two angles whose measures have a sum of 180 degrees. Each angle is called a ___________ of the other. supplement

7. Example 1: Complete the chart.

9. Example 3: The measure of an angle is 10 less than three times the measure of its complement. Find the measure of both angles.

10. A linear pair is two angles which share a side in common and whose noncommon sides form a straight line.

11. Linear Pair Postulate If two angles form a linear pair, then they are supplementary.

12. Example 4: Name all angles that form a linear pair with.
