Talk:Isosceles triangle

Etymology
Can we add the etymology of the word 'isosceles' here? Googling I found that it was "isos ‘equal’ + skelos ‘leg’". I think it aids understanding. Chockyegg (talk) 15:40, 9 October 2014 (UTC)

Usages
Page Punta Cruz Watchtower refers to a "perfect isosceles triangle". Does that mean anything? 112.198.82.241 (talk) 03:17, 20 October 2014 (UTC)


 * I think it's just intended to mean "as opposed to a triangle with two sides nearly equal". Loraof (talk) 16:21, 9 September 2015 (UTC)

Bold in lead
Why is there so much bold in the lead section? Didnt3a (talk) 10:05, 10 October 2021 (UTC)

Internal similarity
I wanted to point out a feature of isosceles triangles but am not sure where it would fit.

If you draw a line perpendicular from any side of an isosceles triangle to the opposite corner, the triangle is subdivided into two similar right triangles. These two triangles are congruent if the perpendicular line is drawn from the iscosceles base. ~Anachronist (talk) 21:12, 8 December 2022 (UTC)

Lewis Carroll died at the beginning of the year 1898.
How could he publish something in 1899? This is a clear mistake, at least unclear information, since there is no reference. If this refers to "Curiosa Mathematica", then it has to be 1890. So I guess it is a typo. 46.114.146.99 (talk) 08:40, 28 February 2023 (UTC)


 * The Lewis Carroll Picture Book was published posthumously. The specific section here was originally intended to be part of Curiosa Mathematica part 3, which was never completed. –jacobolus (t) 04:41, 5 January 2024 (UTC)
