No.

No.

No.
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.
