Statement	Reason
1. WA perpendicular to ZY	Given
2. XB perpendicular ZY	Given
3. ZA = YB	Given
4. < ZAW = < YBX	All perpendicular angles equal 90 degrees
5. WA = XB	Opposite sides of a rectangle are equal
6. triangle ZAW = triangle YBX	SAS property
7. ZW = YX	CPCTC
8. trapezoid WXYZ is isosceles	nonparallel sides are congruent
