Doesn't the rectangle have a rotation symmetry as well? g2? Moberg (talk) 16:31, 13 October 2016 (UTC)

Irregular?

I think having 'irregular' at the bottom is a mistake. The green lines mean 'special case'. The examples in the graphic above the irregular quadrilateral are not special cases of irregular quadrilaterals; they're special cases of quadrilaterals. Could we change 'irregular' -> 'quadrilateral'? --Annielogue (talk) 16:27, 5 November 2018 (UTC)

That sounds very logical, but doesn't result in the best description of a 4-sided shape without symmetries... AnonMoos (talk) 09:23, 7 November 2018 (UTC)
