Geometry

Question Analysis:
This question tests recognition of a specific condition that proves a quadrilateral is a parallelogram.
The main focus is using one pair of opposite sides that are both parallel and congruent.

Key Concept Explanation:
A quadrilateral is a parallelogram if one pair of opposite sides is both parallel and congruent.

Step-by-Step Solution:
Given: WX ∥ YZ and WX = YZ
This satisfies the condition: one pair of opposite sides is both parallel and congruent
So, WXYZ must be a parallelogram

Option Analysis:
A. Kite – Needs two pairs of adjacent congruent sides; not applicable
B. Parallelogram – Correct, matches the condition
C. Trapezoid – Requires only one pair of parallel sides; congruence isn't ne...
