Geometry

Question Analysis:
This question tests recognition of AAS congruence in a diagram.
The main focus is on:
Identifying two angles and their non-included side
Matching corresponding vertices

Key Concept Explanation:
AAS requires:
Two pairs of congruent angles
One pair of congruent sides not between those angles

Step-by-Step Solution:
Given congruent parts:
∠B ≅ ∠E
∠C ≅ ∠F
AB ≅ DE
AB is opposite ∠C → non-included side
Vertex correspondence: A→D, B→E, C→F
