Final answer:
Angles 1 and 2 are adjacent angles that share a common vertex and side, but have no common interior points.
Step-by-step explanation:
Angles 1 and 2 are adjacent angles. Adjacent angles are angles that share a common vertex and side but have no common interior points. In this case, angle 1 and angle 2 share the ray that splits the third quadrant, but they are not vertical, supplementary, or complementary angles.
