The Triangle Inequality Theorem goes as follows:

“The sum of any two side lengths of a triangle is greater than third side length.”

This means that **A and B must be greater than C**. If it isn’t greater, then the triangle’s sides don’t match.

For example: A is equal to 4, B is equal to 3, and C is equal to 7.

**This WOULD NOT be a complete triangle because 4+3=7. **

Let’s try another one: A is equal to 34, B is equal to 21, and C is equal to 50.

**This WOULD be a complete triangle because 34+21=55, and 55 is more than 50.**

Got it? Good!
