one side has to be smaller than the sum of the other two sides and the sum of two sides has to be at least as long as one side. |dw:1345231885219:dw| what happens as x decreases in that triangle on the left? What happens as y increases in the triangle on the right?

Note that if the included angle between the 6 and 9 side was 180 degree only a side < 15 could be used, how is the 18 gonna fit?
