Because it feels like all shapes should choose if they have sides!
Just like boys, girls come in all shapes and sizes.
It can be all kinds of shapes
not all the windows are square. Square is one of the possible shapes.
There are no such shapes because all squares are quadrilaterals - by definition.
You can get all sizes and shapes, but you can just check on Google Images.
All right angle triangles have a square corner
Oh, dude, a square base pyramid is like the cool kid of shapes. It's got that square base, you know, four sides all equal and stuff, and then it's got this pointy top that's like, "Look at me, I'm a pyramid!" So, yeah, it's basically a square with a triangle on top, but way more awesome.
