Answer:
WXYZ is not necessary a parallelogram it is unkown if WC = CY.
Explanation:
Given : Quadrilateral WXYZ .
To find : Which best explains if quadrilateral WXYZ can be a parallelogram.
Solution : We have given that quadrilateral WXYZ .
Given diagonal bisect XZ : CZ = CX
By the property of parallelogram : The diagonals bisect each other.
But we do not have WC = CY
To be a parallelogram it must be equal WC = CY
Then we can not say WXYZ is a parallelogram.
Therefore, WXYZ is not necessary a parallelogram it is unkown if WC = CY.
