+635 All the sides of a triangle are integers. If the perimeter of the triangle is $5,$ then how many different possible triangles are there? (Assume that the triangle is non-degenerate. Two triangles are considered the same if they are congruent.)
+1926 Well, there is actually only 1 possible.
2-2-1 wis the only one that works.
Others wouldn't satisfy the triangle inequality theorems.
Thanks! :)
