Code for my answer to "Exercise: Triangle side lengths" in Dev Bootcamp's Socrates. See the revisions for my original code that was missing some elements and did not work.

Thanks to help on facebook, I realized line 2 needed to be
if a+b>c and a+c>b and b+c>aMy code was only testing for a+b>c, when to test for a valid triangle the values for a, b, and c need to be interchangeable in that equation. So in my original code a triangle with sides a==50, b==100, c==1 would return 'true', when in fact no triangle exists with those side lengths.
