However in certain contexts, it is convenient to allow such
configurations to be dealt with as if they were triangles. In
such a context, they are referred to as "degenerate triangles".

But, in a given context, unless an explicit exception is
declared allowing degenerate triangles, the term "triangle"
implies 3 distinct vertices.
