if M<B=M<D=37, Find M<C so that quadrilateral ABCD is a parallelogram

Answer 1

A parallelogram is a simple quadrilateral with two pairs of parallel sides. The opposite or facing sides of a parallelogram are of equal length and the opposite angles of a parallelogram are of equal measure. Consecutive angles are supplementary. So if one angle is 37, the other one must be 180 less 37 degrees .
