I remember that in Mrs. Cullen's class in 5th grade we talked about the minimum requirements of the three side lenghts to result in a triangle; we were tested on it. I can't for the life of my remember what they were but I remember that the sides had to at least be in certain proportions with eachother...like odd triangles that had a huge side needed to have another one and then a smaller one...;;;
Say you have one huge side. Remember that a line is the shortest way to get from any two points (in this case, the intersections on either end of the huge side). Therefore, the other two (short) sides are a less direct way from the two intersection points, so they must have a combined length of greater than the huge side.
That seems to ring a bell and really helps; Thank you, Scott :)
