phalangites or pezethairoi

[jerby]

Thanks NeonGod, yeah like I said all Squares have 4 90 degree angles and 4 sides. All Quadrilaterals have 4 sides and 4 vertices, a square is a very specific type of quadrilateral (which by the way is a type of polygon).

you lost me there, but what i do follow is this
global->specific
quadrilateral->squares->rectangle

so every rectangle is a square (specific->global) but not all squares are rectangles. right??

this is the weirdest off-topic yet..from pezetairoi to geometry
