Which inequality can be used to explain why theses three segments cannot be used to construct a triangle

Let a, b, c represent the lengths of each side of the triangle. It would be a<b+c b<a+c, and c<a+b.

Step-by-step explanation:

Just insert the lengths of the sides into the inequality and it will make the inequality false. The reason behind it is that each side cannot be greater than the other 2 sides combined. Otherwise the two sides cannot connect with both ends of the third side.
