Angles are complimentary or supplementary. Lines aren't.
Alternate and supplementary
In the context of two parallel lines and an intercept, they are called interior angles.
supplementary
They are if parallel lines are cut by a transversal that's perpendicular to them.

supplementary
They are if parallel lines are cut by a transversal that's perpendicular to them.
It has two pairs of parallel sides.Its adjacent angles are supplementary.
The angles formed are supplementary, equal corresponding and equal alternate angles
Their angles of intersection are the same, and the angles facing each other are supplementary.
