Three lengths can make a triangle if the sum of the two smallest numbers is greater than the largest.

Example 1:
8,10,12 YES: 8+10=18 is greater than 12
Example 2:
4,7,12 NO: 4+7=11 is less than 12
Example 3:
5,6,11 NO: 5+6=11 is not GREATER THAN 11

You can figure out the answers for each set of lengths in this problem.
