Answer:
Step-by-step explanation:
8. No, the 2 angles 5 and six do not make a linear pair. A linear pair is when two angles add up to 180 degrees and create a line. 5,6, and 7 would be a linear pair, since the sum of the 3 make a line.
9. Yes, 5 and 9 make a linear pair. If you look closely, you can see they make up the line going diagonally up left.
10. No. Although 5 and 8 are adjacent angles and thus, equal, they do not make up a line.
11. Yes, they are vertical angles.
12. No, though they do seem to be similar, they are not adjacent to each other.
13. No, 9 and 6 are not vertical angles.
Hope this helps!
