# how to close a duplicate of a stackoverflow question? [duplicate]

The question Finding third side of a minimal triangle appears to be essentially a duplicate of https://stackoverflow.com/questions/22441855/triangle-circle-enclosing-a-set-of-points .

The stackoverflow question has detailed answers with references, for this nontrivial problem.

If it is a duplicate (which is not yet entirely clear, since the question is itself not entirely clear), should it be closed (I think yes), and if so, how? The option to close as duplicate does not work -- it says "The duplicate question must exist on Mathematics Stack Exchange".

(Sorry if this has been asked before, but I couldn't find it -- just close as a duplicate if it has!)

• Not to mention the context makes the questions completely different. Have you noticed that both answers of the SO question are explaining that the algorithm is $O(n)$ and so on? Whereas this kind of consideration is non-existent in the math.SE thread. – Najib Idrissi Sep 3 '16 at 15:16
