3. 49+ 131 +49 + m<x = 360 substitution property of equality
4. 229+ m<x = 360
5. m<x= 131
6. <X ≅ <Z and <W ≅ <Y Angles with equal measures are congruent
7. WXYZ is a parallelogram.
Match the statements to the equation
The sum of interior angles of a quadrilateral is 360 degrees
Subtraction property of equality
A quadrilateral with opposite angles congruent is a parallelogram
Simplify (combine like terms)
