Squares

So there are two (or more) sayings with squares. "Be there or be square." and "Play fair and sqaure." So if you're not there, then you are a fair person. If you play fair, then you're a loser for not being there. . . . . Squares are cool! Until your teacher say they are rectangles! No they are not! Apparently, a sqaure can be a rectangle but a rectangle cannot be a square? What's that all about?! They are two completely different things. They are similar, but different! "A square is a rectangle because they both have four right angle, and congruent/equal opposite sides." Why doesn't it work the other way around? I don't know, but apparently your teacher does. Nowadays I think squares are given less credit than they should get. A square can't be two things people! Ok I'm done! ^-^
