So, 3 angles form a line.
Are these 3 angles supplementary angles? If not, what are they?
-
they are supplementary. 180* = a line

Angles are supplementary if their sum is 180 degrees. And because those angles form a line, which is straight, instead of an angle or triangle, I would suppose that they might be supplementary.

If I remember correctly, supplementary angles make 180* and complementary angles make 90*.
