Geometry

Question Analysis:
Explores the role of angles in polygon congruency.

Key Concept Explanation:
Square: All angles = 90°.
Rhombus: Angles ≠ 90° unless it’s a square.
Congruency requires both sides and angles to match.

Step-by-Step Solution:
Both have equal sides, but a rhombus has non-90° angles unless it’s a square.
They’re congruent only if the rhombus is also a square (angles = 90°).

Option Analysis:
A: Incorrect. Only true if the rhombus is a square.
B: Correct. Angles must match.
C: Incorrect. Ignores angle requirements.
