1. Geometry 3.4 adjacent angles and linear pairs

2. Adjacent Angles are angles that share a common side and have the same vertex, but have no interior points in common.

3. Are 1 and 2 adjacent angles? M B N 1 2 L 1 2 B 1 2 H 12 U 12

4. Linear Pairs Two angles form a linear pair if and only if they are adjacent AND their non-common sides are opposite rays.
