Supplementary angles
From Wikipedia, the free encyclopedia
Look up supplementary in Wiktionary, the free dictionary.
A pair of angles are supplementary if their respective measures sum to 180 degrees.
If the two supplementary angles are adjacent (i.e. have a common vertex and share a side, but do not have any interior points in common) their non-shared sides form a line.
