Answer:
1. vertical angles: <2 and <5
2. Supplementary angles: <6 and <2
Explanation:
Vertical angles are angles that are opposite to each other
-they will always have the same measure
-examples from the picture: 2 and 5, 6 and 1, 3 and 8, 7 and 4
Supplementary angles are angles that add up to 180
-they will always be able to form a straight line
-examples from the picture: 1 and 5, 6 and 2, 1 and 2, 5 and 6, 3 and 7, 7 and 8, 3 and 4, 8 and 4
