Question Analysis:
This question involves understanding the SAS Congruence Postulate, which is a fundamental concept in triangle congruence.
The main focus is on identifying the correct set of congruent parts needed to apply this postulate.

Key Concept Explanation:
The SAS Congruence Postulate states that if two sides and the included angle of one triangle are congruent to two sides and the included angle of another triangle, then the two triangles are congruent.

Step-by-Step Solution:
Examine each option:
Option A: Two sides and a non-included angle → Not sufficient (This describes SSA, which does not guarantee congruence).
Option B: Two sides and the included angle → Correct (This matches the SAS Congruence Postulate).
Option C: Two angles and a non-included side → Not sufficient (This describes AAS, not SAS).
Option D: Three sides → Not SAS (This is SSS Congruence Postulate).
The correct answer must match the definition of SAS, which is O...
