The lengths of two sides of a triangle are 3 centimeters and five centimeters write an inequality to represent the range of values for the third side

There exists one simple and interesting conclusion for triangle, that is the sum of any two sides's length are longer than the other side and the difference between the length of any two sides is smaller than the other side, If, we use L to denote the length of the third side, we can conclude that: 5-3
