mihalych1998 [28]

Answer:

1. Supplementary and Linear pair, 2. Adjacent, 3. Adjacent, 4. Complementary and adjacent, 5, Vertical, 6. Adjacent

Step-by-step explanation:

1. is a Linear pair because the two angles form a straight line, this means they are also supplementary because the two angles must add up to 180 degrees which is a straight line.

2. Are adjacent angles, because they share a common side and do not share any interior points.

3. Are adjacent angles, because they share a common side and do not share any interior points.

4. These angles are complementary and adjacent. They both sum to 90 degrees which makes them complementary. They are also adjacent angles, because they share a common side and do not share any interior points.

5. These are vertical angles because they are opposite angles made by intersecting lines.

6. Are adjacent angles, because they share a common side and do not share any interior points.
