31.
[4] 1 and 2 are supplementary, because it is given. So, m1  m2  180 by the definition
of supplementary angles. 1  3 because it is given. So, m1  m2 by the definition of
congruent angles. By the Substitution Property, m3  m2  180, so by the definition of
supplementary angles, 3 and 2 are supplementary.
