Geometry

Question Analysis:
Tests application of SAS with numerical values and a clear included angle.

Key Concept Explanation:
SAS is confirmed when two sides and the included angle are equal.

Step-by-Step Solution:
Given:
PQ = ST = 9 in (Side)
QR = TU = 12 in (Side)
∠Q = ∠T = 70° (Included Angle)
Verification: The 70° angle lies between PQ & QR and ST & TU.
Conclusion: SAS proves congruence.

Option Analysis:
(A) ASA → Incorrect (Only one angle given).
(B) SAS → Correct (Fits the pattern).
(C) AAS → Incorrect (Needs tw...
