I came across a question by a new user where he had asked a question and answered it himself right away (since he had read the guidelines that says that this is encouraged).
The question which was a very basic geometry question was quickly closed as off-topic (it only said "Prove this: (theorem)").
OP asked how to get it reopened so I'm asking it here. My questions are:
What should OP do to get the question reopened in this case? Normally I would ask OP to add his/her own approach to the problem, but asking OP to do this seems a bit artificial when he has already answered it.
Should questions that are asked and answered at the same time be closed as off-topic even if they are on the homework-form?
