Mathe the statement to the equation

1. The sum of the interior angles of a quadrilateral Is 360 degrees
2. Simplify (combine like terms)
3. Subtraction property of equality
4. A quadrilateral with opposite angles congruent is a parallelogram

m<y+ m<z+ m<w+ m<x= 360

229+ m<x = 360

m< x = 131

WXYZ is a parallelogram

m<W = m<Z and m<X = m<Y
