Talk:Incircle and excircles

I check pages listed in :Category:Pages with incorrect ref formatting to try to fix reference errors. One of the things I do is look for content for orphaned references in wikilinked articles. I have found content for some of :Incircle and excircles of a triangle's orphans, the problem is that I found more than one version. I can't determine which (if any) is correct for this article, so I am asking for a sentient editor to look it over and copy the correct ref content into this article.

Reference named "etc":

• From Feuerbach point: [http://faculty.evansville.edu/ck6/encyclopedia/ETC.html Encyclopedia of Triangle Centers] {{webarchive |url=https://web.archive.org/web/20120419171900/http://faculty.evansville.edu/ck6/encyclopedia/ETC.html |date=April 19, 2012 }}, accessed 2014-10-24.

I apologize if any of the above are effectively identical; I am just a simple computer program, so I can't determine whether minor differences are significant or not. AnomieBOT⚡ 16:45, 23 January 2017 (UTC)

I question the relevance of the recent addition of Exsecant and excosecant to the "See also" section. What do these rarely used functions have to do with the incircle and excircles?—Anita5192 (talk) 19:53, 12 August 2017 (UTC)

:Since there was no response, I have removed the redundant links.—Anita5192 (talk) 02:16, 15 August 2017 (UTC)

It is stated that the two equations in the Euler's theorem section are similar.

But the left side of equations have different signs.

:The two equations are identical except for that one sign. Hence, they are similar.—Anita5192 (talk) 00:01, 2 May 2020 (UTC)
