Answer:
a.) 2 & 3
b.) 7 & 8
Explanation:
Vertical angles are angles that are across from each other when there is a traversal line.
Supplementary angles are two angles that add up to 100 degrees.
Supplementary: 1 and 2, Vertical: 7 and 6
Supplementary angles add to 180 degrees. If you take away the line between 1 and 2, you would have an angle of 180 degrees. Vertical angles are opposite each other inside the rays of an X.
