You do not provide the sets of sides. I will explain to you how to do it.
For a set of sides to make a triangle, the sum of the two smallest numbers must be bigger than the largest number.
Example 1: 3, 6, 7 (Set of sides)
3+6=9
9 is greater than 7
This set of sides will make a triangle
Example 2: 5, 7, 14 (Set of sides)
5+7=12
12 is less than 14
This set of sides will not work
