English naming
I need help from natural english speakers:
In german we have "Viereck" for a 2D figure with 4 corners and "Rechteck", if all 4 corners are 90 degree. My first internet search tells me, that "rectangle" is for both in english. But now I'm unsure.
- What is the usual (demotic) word for "Any 2D figure with four corners"?
- And what is the mathematical word? (quadrilateral?)

- In English there is a square and a rectangle, a square is the shape that has 4 sides of the same length with 90 degree angles, whilst a rectangle is the shape with two sides that are longer than the other two. Quadrilateral is indeed the mathematical word for any shape with four sides and four vertices (corners). I think this is what you want to know, if not then I apologise. Hope this helps! -- WorldsBoss (talk) 12:02, 22 October 2013 (UTC)
- Now I have found "quadrangle"? is this the right word for the new model? -- Wiimm (talk) 12:29, 22 October 2013 (UTC)
- Well, I've never come across the word quadrangle before, so I suppose we'll need some further input. I think quadrilateral should be fine :P -- WorldsBoss (talk) 12:56, 22 October 2013 (UTC)

About the new model
I like the new model, because it can explain most of the position jump bugs. Overall I'm surprised, because I (and the whole ct community?) thought, that superimposed parts will always results in a position bug, because the check points are define in 2D. And now I hope, that the tack authors will read the page and use the new model to fix the tracks.
