The rule for determining if three length can make up a triangle is to consider the length of any of the two and compare with the third length to check if it's greater.

mathematically, assume that a, b, c are three lengths. they will only form a triangle if these three conditions are true.

a + b > c;

b + c > a;

a + c > b;

That is the reason the only 3,7,14 cannot form a triangle because 3 + 4 < 14
