Question Analysis:
This problem applies the SSS Congruence Postulate in a real-world engineering context.
The main focus is on ensuring structural alignment using congruence principles.

Key Concept Explanation:
SSS Congruence Postulate states that if three sides of one triangle are equal to the corresponding three sides of another triangle, then the two triangles are congruent.
Congruence means the two triangles are identical in shape and size, ensuring they fit together perfectly in construction.

Step-by-Step Solution:
The problem states that all three sides of the two plates match exactly.
Since the triangles have identical side lengths, we can immediately apply SSS Congruence.
By definition of congruence, the two plates must be identical in shape and size, ensuring a perfect fit.

Option Analysis:
A) Correct. The SSS Congruence Postulate guarantees that both triangles are identical in shape and size.
B) Incorrect. Similarity only applies when sides are proportional, not exactly equal.
C) Incorrect. Even if the pl...
