Geometry

Question Analysis:
This question evaluates understanding of the SAS postulate in real-world contexts, emphasizing the included angle requirement.

Key Concept Explanation:
SAS requires the angle to be between the two given sides.
Non-included angles (SSA) do not guarantee congruence (e.g., the "Ambiguous Case" in trigonometry).

Step-by-Step Solution:
Plot X: 8 m, 60°, 10 m → SAS (angle is included).
Plot Y: 8 m, 10 m, 60° (non-included) → SSA (invalid for congruence).
Conclusion: The triangles are not necessarily congruent because the angle placement differs.

Option Analysis:
(A) Incorrect – Assumes all parts match, but angle position matters.
