Many times the OP posts a problem hoping to find an "elementary" solution but the answers use trigonometry. The OP may understand trigonometry but wants a pure geometrical solution or he may be in middle school and have no idea what is trigonometry. This happened yesterday: in this question, Michael Rozenberg posted a solution using trigonometry then had to write another one without trigonometry after the OP said he doesn't know what $$\sin$$ is. Then user xpaul posted the same solution of Michael (using the law of sines) after an hour. In another question yesterday, users Deepak and Paracosmiste answered using trigonometry but the OP preferred not to used trigonometry so Paracosmiste had to write another answer without trigonometry. The tag geometry-without-trigonometry will hopefully let us avoid such problems just like limits-without-lhopital did.
