Geometry

Question Analysis:
This practical problem tests recognition of when ASA applies in construction scenarios.

Key Concept Explanation:
ASA congruence requires:
Two angles and their included side
Here: 65° angle, 12" side, 45° angle (included between them)

Step-by-Step Solution:
Identify given elements:
Two angles (65° and 45°)
The 12-inch side is between them
This exactly matches ASA requirements
No other postulate fits these conditions

Option Analysis:
A. SSS needs three sides - not given
B. SAS needs two sides and included angle - only one side given
C. Correct - matches angle-side-angle...
