| Apr 20 at 22:01 | comment | added | Alma Arjuna | @DanUznanski yes, I see that! But the reason I found quadrilaterals to be interesting was exactly because, since we have four sides, there could be some symmetrical disposition for the angles defining it, something not possible for general polygons | |
