What is the name of the relationship between 4 and 8?
a.
adjacent
b.
alternate interior
c.
alternate exterior
d.
corresponding

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.

“exterior angles of triangles. an exterior (or external) angle is the angle between one side of a triangle and the extension of an adjacent side. try this drag the orange dots on any vertex to reshape the triangle.” look to get to the answer i explained what it means and other things i hope it you .
