Answer:
B: ∠3 and ∠6
Explanation:
The way the angles are numbered on this diagram, alternate interior and alternate exterior angle numbers total 9. Exterior angles are outside (not between) the "parallel" lines.
In the answer choices, you have angle number totals of ...
A: 3+2=5
B: 3+6=9 . . . . these are the angles of interest
C: 2+7=9 . . . these are alternate interior angles
D: 6+8=14
_____
Additional comment
"Alternate" means the angles are on opposite sides of the transversal.
"Interior" means the angles are between the "parallel" lines.
"Exterior" means the angles are outside the "parallel" lines.
"Consecutive" or "same-side" means the angles are on the same side of the transversal. Interestingly, both interior angles and exterior angles can be "consecutive".
