This is a short powerpoint about angle addition postulate and how it can be used with two angles in various situations.

1. How Angles Add Up! Angle Addition Postulate

2. Angle Addition Postulate Add two angles together to create a larger angle. Or subtract a smaller angle from a larger angle to find an angle measure.

3. Complementary Angles You can identify complementary angles by the two adjacent angles that cover a right angle. The right angle mark is in red to make it easier to identify.

4. Supplementary Angles Supplementary angles are two angles that sum to 180o. These angles do not have to be adjacent angles.

5. Linear Pairs Linear pairs are angles that are adjacent and supplementary. They get the name “linear” because these angles create a line.
