Answer:
- Supplementary
- Adjacent
- Linear pair
Step-by-step explanation:
1. Supplementary - angles whose sum is 180 degrees.
In that case, a+b form a straight angle (180 degrees).
2. Adjacent - angles with a common vertex AND a common side.
3. Linear pair - angles that form a straight angle (180 degrees).
The difference between supplementary angles and linear pair:
1. Linear pair angles MUST be adjacent.
2. Supplementary angles NEED NOT to be adjacent.
