Geometry

Question Analysis:
This question tests understanding of polygon congruency beyond triangles, emphasizing that side lengths alone are insufficient.

Key Concept Explanation:
For quadrilaterals, congruency requires both sides and angles to match.
Example: A rectangle and a kite can have identical side lengths but different angles.

Step-by-Step Solution:
Option A: False (angles may differ; e.g., rectangle vs. kite).
Option B: False (could be a kite, which is not always a parallelogram).
Option C: False (angles are not determined by sides alone).
Opt...
