By the definition of supplementary,
MZA+ m2D = 180. Using side vas a transversal,
ZB and C are same-side interior angles, so they are
supplementary. By the definition of supplementary,
m2B + m2 = 180. So, mzA + m2D + m2B + m2 =
180 + 180 by the
M property. Simplifying,
we have m A+ m2B + m2 + m2D = 360°.
