Geometry

Question Analysis:
This question evaluates understanding of corresponding parts in SAS congruence.

Key Concept Explanation:
When triangles are congruent via SAS:
The first named sides are congruent (AB ≅ DE).
The second named sides are congruent (BC ≅ EF).
The named angles (∠B ≅ ∠E) must be between those sides.

Step-by-Step Solution:
Given: ΔABC ≅ ΔDEF by SAS.
Correspondence Rules:
The order of letters implies:
AB ≅ DE (first sides), BC ≅ EF (second sides).
∠B ≅ ∠E (angles between the sides).
Conclusion: The statement is true because SAS dictates this exact correspondence.
