    It's assumed that anyone attempting this challenge understands basic Geometry. Any rules will be stated in the Problem Statement at the top of the page. The Explanation section is not stating a rule, it's stating an inequality relevant to the respective A, B, and C values for that Sample Case. The reason why those values do not form a triangle is because 27 is a number that is less than 30. There is a difference between the two numbers. If A and B added up to 30, then the Explanation would say that A + B = C because that would be the immediate reason causing it to not be a triangle.
