14.) b

15.) a

Step-by-step explanation:

11.) a) because the two <4 and <9 are alternate exterior angles and 4 is on line d and 9 is on line e, so it would be d || e.

12.) b) because <20 and <21 are consecutive interior and <20 is on line and <21 is on line b, so it would be a || b.

13.) c) They're alternate interior and <10 is on line b and <23 is on line c, so it would be b || c

14.) b) They're alternate exterior and <1 is on line d and <10 is on line e, so d || e

15.) a) They're corresponding angles and <13 is on line a and <17 is on line c, so a || c
