Question

When three side lengths can form a triangle that triangle is considered what
Unique
Nonunique
Impossible

Answer 1

When three side lengths can form a triangle, that triangle is considered **nonunique**. This is because there can be multiple triangles that share the same set of side lengths, especially if the side lengths allow for different arrangements or types of triangles (e.g., scalene, isosceles, equilateral).

Additionally, the terms "unique" and "impossible" wouldn't apply to the scenario of forming a triangle with the given side lengths. "Unique" would imply only one possible triangle can be formed from those side lengths, which is not the case. "Impossible" would mean the lengths cannot form a triangle, which is not applicable if we know they can.

Thus, the correct answer is **nonunique**.
