Answer:
Corresponding
Step-by-step explanation:
So, we know that 1&2, 3&4, 5&6, and 7&8 all equal 180 degrees in their pairs. 7&3 are corresponding angles that are less than 90 degrees on their own. We don't know the degrees of each angle, so we can't say their exact angle.
(I know I didn't give the second answer, if you elaborate, maybe I can understand what it's asking better)
Hope this helped!
