I read on a website that someone had had a geometry class where they had to find a polygonal shape with four edges of which two were parallel and only one right angle. They couldn't do it, and it turned out the whole question was wrong.
I am quite sure such a shape is impossible. The two parallel edges can't have an angle between them, so they must both have an angle with a third edge. However, because the edges are parallel, either both or neither of these angles are right.

I'm trying to understand how eliminations work under Single transferable vote. Sometimes it's possible to eliminate a whole group of candidates in a single count if it's clear that their elimination separately could not affect the outcome of the vote. What I don't understand is, how do you find this group? Is there somewhere that explains the algorithm? Thanks, 78.19.190.3 ( talk) 22:21, 20 August 2020 (UTC)
If there is only one position to be filled then STV would not be used. See third sentence of paragraph 7 of the Wikipedia article. — Preceding unsigned comment added by 82.38.235.128 ( talk) 09:03, 23 August 2020 (UTC)
How do the edge cases work? Given this concrete example on count one with a quota of 101:
Candidate | C1 | C2 | C3 | C4 | C5 | C6 | C7 | C8 | C9 | C10 | C11 | C12 | C13 |
---|---|---|---|---|---|---|---|---|---|---|---|---|---|
Votes | 1 | 1 | 1 | 1 | 1 | 1 | 95 | 100 | 100 | 100 | 100 | 100 | 100 |
Which candidates get excluded on the first count and why? Obviously you'd start with the candidates with one vote, but can you do all six as a group or would you have to do them one at a time? 93.107.224.16 ( talk) 14:15, 24 August 2020 (UTC)
