Final answer:
The statement that is true about the relationship between rectangle ABCD and rectangle WXYZ is AB = WX. In rectangles, opposite sides are equal in length.
Step-by-step explanation:
The statement that is true about the relationship between rectangle ABCD and rectangle WXYZ is:
AB = WX
In rectangles, opposite sides are equal in length. Therefore, if AB = WX, it means that the length of AD is equal to the length of XZ. The other statements, DA = XZ, CBC = YZ, and BDC = XY, are not true for the general relationship between rectangles.
