Geometry

Question Analysis:
Focuses on the importance of angle equality in SAS.

Key Concept Explanation:
SAS requires both sides AND the included angle to be identical.

Step-by-Step Solution:
Given: Both triangles have sides 5 cm and 7 cm.
Included angles are 30° vs. 45° → Not equal.
Thus, not congruent by SAS.

Option Analysis:
(A) Incorrect – Angles must match.
(B) Correct – Different angles violate SAS.
(C) Incorrect – SSA is invalid.
