Geometry

Question Analysis:
This question focuses on properties of congruent triangles.
The main focus is on identifying the fundamental properties of congruency.

Key Concept Explanation:
Congruent triangles have equal corresponding sides and angles, leading to equal perimeters and areas.

Step-by-Step Solution:
Since corresponding sides are equal, the perimeter (sum of sides) is equal.
Since corresponding angles and sides are equal, the area remains unchanged.
All three statements must be true, so the correct answer is D.

Option Analysis:
A) True, as congruent triangles have the same area.
B) True, as corresponding sides...
