Answers:
- a
- b
- consecutive interior angles converse
===================================================
Explanation:
Ignore lines c and d.
The angles 94 and 86 add to 94+86 = 180 to show that they are supplementary, which then lets us use the consecutive interior angles converse to prove that line 'a' is parallel to line b
The term "same side interior" can be used in place of "consecutive interior". We're using the converse because the original theorem says that if line 'a' is parallel to line b, then those two angles are supplementary. So we're taking this logic in reverse.
