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!
