How to determine if three lengths make up a triangle

The video tutorial explains how to determine if given side lengths can form a triangle using the triangle inequality theorem. It introduces the concept, explains the theorem, and demonstrates its application with examples. The key idea is that the sum of any two side lengths must be greater than the third side length for the sides to form a triangle.

Can you provide an example of three lengths that can form a triangle? Explain your reasoning.

What conclusion can you draw if the sum of two side lengths is not greater than the third side?
