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.
