Geometry

Question Analysis:
This question involves the application of CPCTC (Corresponding Parts of Congruent Triangles are Congruent).
The main focus is on correctly identifying the corresponding sides and angles of two congruent triangles.

Key Concept Explanation:
CPCTC states that if two triangles are congruent, then their corresponding sides and corresponding angles are congruent.
When we write △ABC ≅ △DEF, the order of the vertices matters.
A corresponds to D, B corresponds to E, and C corresponds to F.
So, AB corresponds to DE, BC corresponds to EF, and ∠B corresponds to ∠E.

Step - by - Step Solution:
Given △ABC ≅ △DEF.
For corresponding sides:
Since AB = 5 cm and AB corresponds to DE, then DE = 5 cm.
Since BC = 7 cm and BC corresponds to EF, then EF = 7 cm.
For corresponding angles:
Since ∠B = 60° and ∠B corresponds to ∠E, then ∠E = 60°.

Option Analysis:
Option A: DE = 5 cm, EF = 7 cm, and ∠E = 60° is correct as per the above - explained correspondence.
Option B: Here, the side correspondence is wrong. DE should be 5 cm and EF should be 7 cm, not the other way around, so this option is incorrect.
Option C: The wrong sides and angles are being matched. DF does not correspond to AB in the given congruence statement, and ∠D does not correspond to ∠B, so this option is incorrect.
Option D: Similar to option C, the wro...
