Answer:
Step-by-step explanation:
1) b/c not parallel because they are perpendicular
2) b/c are parallel because both on line c 180-110=70
3)b/a are parallel because the opposite exterior angles are the same degrees
4) a=90 b=78 c=not shown d=116 e=116 f=102
5) top=92.95 degrees bottom =87 degrees
6)top=130 deg bottom =50 degrees
