Geometry

Question Analysis:
This statement tests whether students understand the precise requirements of the SAS Congruence Postulate, particularly the included angle condition.

Key Concept Explanation:
SAS Congruence Postulate requires:
Two pairs of congruent sides.
The included angle (the angle between the two sides) must be congruent.
Non-included angles (SSA) do not guarantee triangle congruence.

Step-by-Step Solution:
Given: Two triangles with:
Two pairs of congruent sides (e.g., AB = DE, BC = EF).
One pair of congruent angles (∠A = ∠D).
Check Angle Position:
If the angle is not between the two sides (e.g., ∠A is opposite side BC), this is SSA, not SAS.
SSA is not a valid congruence rule (except for right triangles via HL).
