FLASHCARD QUESTION

Front

How are supplementary angles related to a triangle?

Back

While individual angles in a triangle are not supplementary, any two angles in a triangle can be considered supplementary when combined with the third angle. For example, if you have angles A and B in triangle ABC, then A + B + C = 180°. Therefore, A + B can be considered supplementary to angle C.
