 For a shape to be a triangle at all, all sides have to be of length > 0, and the sum of the lengths of any two sides must be greater than or equal to the length of the third side.
 
+~~~~exercism/note
+_Degenerate triangles_ are triangles where the sum of the length of two sides is **equal** to the length of the third side, e.g. `1, 1, 2`.
+We opted to not include tests for degenerate triangles in this exercise.
+You may handle those situations if you wish to do so, or safely ignore them.
+~~~~

 In equations:
 
 Let `a`, `b`, and `c` be sides of the triangle.
