Geometry

Question Analysis: This question focuses on the fundamental properties of triangles and polygon congruency.

Key Concept Explanation:
A unique triangle can be formed if the three given sides satisfy the Triangle Inequality Theorem, which states that the sum of the lengths of any two sides must be greater than the length of the third side.

Step-by-Step Solution:
Check if the three given sides satisfy the triangle inequality:
If a + b > c, a + c > b, and b + c > a, a unique triangle is formed.
If this condition is met, no other triangle can be formed with these three sides.

Option Analysis:
(A) Correct: The Triangle Inequality Theorem guarantees a unique triangle.
(B) Incorrect: Not all three sides form multiple tria...
