Question

What is the name of the relationship between 4 and 8?

Answer 1

4 and 8 are corresponding angles.

The easiest way to tell is to look at the two groupings: 1, 2, 3, 4 and 5, 6, 7, 8. 4 and 8 are in the same position in both groupings (bottom right corner). This makes them corresponding.

Adjacent angles would have a common side and vertex. This would be like 4 and 2 or 1 and 3 or 5 and 7 or 8 and 6.

Alternate interior angles would be opposite angles inside the parallel lines. This would be like 4 and 5 or 3 and 6. 

Alternate exterior angles would be opposite angles outside the parallel lines. This would be like 2 and 7 or 8 and 1.

Answer 2

No it's alternate exterior corresponding is the angles that occupy the same relative position at each intersection where a straight line crosses two others. If the two lines are parallel, the corresponding angles are equal.
