| Aug 11, 2011 at 22:19 | comment | added | Michael Hardy | The nature of the set of cyclic polygons having a particular sum of squares of sides seems not as interesting as the set of cyclic polygons having a particular sum of squares of sides and a specified diameter of the circumscribed circle. | |
| Aug 3, 2011 at 1:08 | comment | added | Michael Hardy | So I'm thinking I should ask myself what the sets $\{(\alpha_1,\dots,\alpha_n)\;:\; \alpha_1+\cdots+\alpha_n = \pi,\ \sin^2\alpha_1+\cdots+\sin^2\alpha_n = c\}$ look like. | |

We'll see if this succeeds in making "align" work on this site. (It's unproblematic on stackexchange.)

| Jul 31, 2011 at 0:02 | comment | added | user6976 | @Gjergji: This is an interesting problem. "Elementary" problems about polygons arise all the time when geometry of surfaces is considered, for example. | |

| Jul 30, 2011 at 23:40 | comment | added | Gjergji Zaimi | Dear Michael, I think that such questions are interesting, but not appropriate for MO. My reasoning is simply based on the fact that one is more likely to encounter such a problem when (for example) preparing for contests rather than in mathematical research or teaching etc. I would suggest artofproblemsolving as a good place to discuss similar questions. | |
