    A triangle has to have the sum of the lengths of the two smaller sides greater than the largest side. So, the 3-in stick would not be possible because 3 + 3 is equal to 6, not greater than it. Also think about it how having two sides being equal to the longest one, the sides would have to be directly on the last one for it to possibly be connected.
