Geometry

Question Analysis:
Tests identification of AAS requirements in diagram contexts.

The main focus is on:
Selecting the missing angle to complete AAS
Verifying side position

Key Concept Explanation:
AAS requires: Two angle pairs; One non-included side pair
BC is opposite ∠A → non-included side

Step-by-Step Solution:
Given:
∠A ≅ ∠D
BC ≅ EF (non-included)
Need second angle:
∠B ≅ ∠E completes AAS

Option Analysis:
A) Corre...
