Deletion of Dao's theorem

Comment: Alright there are some obvious major issues with this. One is the naming. No independent source actually refers to any of these statements as "Dao's Theorem," so the title has to be changed. You can't name a theorem after yourself. Second, not all of these statements are notable, so the article reads like a summary of the work of Dao, a non-notable amateur mathematician. However I think some  of the work is interesting and possibly significant. {{ping|Eightcirclestheorem}} Perhaps you should userfy the whole article and incorporate the generalization of Goormaghtigh's Theorem as a separate section in a new article about that theorem. Also please note that notability is based on citations or mentions in independent texts. See . Some things may not be notable simply because they are too new to have received attention. It's not a criticism of the merit of the work

Comment: to Dao's eight circles problem. This article is now a dab page, but Dao's eight circles problem seems to be the only article that will be kept, so a dab page is not needed. Even if Dao's six circumcenter theorem is also kept, a redirect and hatnote are still appropriate. However, none of these theorems satisfy , so I would also be !voting "delete" on Dao's six circumcenter theorem and Dao's eight circles problem if they came up for AfD. -- Special:Contributions/120.23.70.34|120.23.70.34
