Question Analysis
This question involves recognizing the implications of SSS congruence.
The main focus is on understanding what else must be true when triangles are congruent.

Key Concept Explanation
Congruent triangles have exactly the same shape and size.
If triangles are congruent, both their corresponding angles and sides must be equal.

Step-by-Step Solution:
Analyze the implications of triangle congruence:
A (Corresponding angles are congruent) → True, since congruent triangles have the same shape. ✅
B (Perimeters are different) → False, since congruent triangles have equal side lengths, their perimeters are al...
