Geometry

Question Analysis:
This question tests the ability to identify the correct congruence postulate when given two sides and an included angle.

Key Concept Explanation:
SAS Postulate (Side-Angle-Side): Two triangles are congruent if two sides and the included angle of one triangle are equal to the corresponding parts of another.
Critical Detail: The angle must be between the two sides.

Step-by-Step Solution:
Given:
AB = DE (Side)
∠B = ∠E (Angle)
BC = EF (Side)
The angle (∠B = ∠E) is between sides AB & BC and DE & EF.
This matches the SAS condition.

Option Analysis:
(A) SSS → Incorrect (No info about AC = DF).
(B) SAS → Correct (AB, ∠B, BC match DE, ∠E, EF).
(C) ASA → Incorrect (Requires two angles a...
