Answer:
Step-by-step explanation:
1 and 2 are corresponding angles, it's B because corresponding angles are always congruent.
In this little picture i drew up 1 and 2 are corresponding. meaning they're in the same places where the transversal crosses both parellel lines. the same goes for angles 3 and 4, 8 and 5, 7 and 6
Angles 3 and 6 are consecutive exterior angles, and those are supplementary, meaning that they add up to 180 degrees. 1 and 5 are the same way
Angles 2 and 8 are consecutive interior angles, and those are also supplementary. angles 7 and 4 are the same way.
Angles 7 and 2 and 8 and 4 you can see those are crossing on the inside, those are called alternate interior angles, and these angles are congruent to one another. meaning that 7 and 2 are congruent to one another, and 8 and 4 are also congruent, or equal to one another
Angles 3 and 5 and 1 and 6 are what as known as Alternate Exterior Angles. Those angles are on the outside part of the intersection and they are congruent if cut by a transversal. meaning that 3 and 5 are equal to one another and so is 1 and 6.
Hope this helped clear it up a bit more. Sorry if i just made you more confused
