The 3 interior angles of a triangle add up to 180 degrees

The sum of all angles in a triangle always add up to 180 degrees

No, a triangle cannot have two angles. Triangles always have three sides and three angles that add up to 180 degrees.

The three interior angles of a triangle add up to 180 degrees.

This question could be argued over and over. However, my interpretation of "supplementary" is TWO angles add up to be 180. However, there are THREE angles in a triangle, so the angles of a triangle, although they add up to 180, are not supplementary.
