How to determine if three lengths form a triangle

The video tutorial explains how to determine if three side lengths can form a triangle using the triangle inequality theorem. It introduces the concept, defines side lengths a, b, and c, and explains that the sum of any two sides must be greater than the third side. An example is provided to illustrate incorrect side lengths that do not form a triangle. The video concludes with a recap of the key points.

What is the significance of the statement 'the sum of two sides must be greater than the third side'?
