The sum of all three angles of a triangle, each of which is greater than 0 degrees, is 180 degrees. So two of them cannot add to 180 deg.

No, they are complimentary (add to 90°) Supplementary means the two angles add to 180°
No, they are complementary angles. Supplementary angles sum to 180o Complementary angles sum to 90o. The three angles of a triangle sum to 180o. If one is 90o (the right angle), then the other two sum to 180o - 90o = 90o and so are complementary.
Two acute angles cannot be supplementary but they can be complementary
Supplementary angles are two angles which add up to 180°.
Supplementary angles total 180 degrees.
