Shapes. Circle square triangle cube . The world of shapes is very strange. I never really thought much about it. A box is square a ball is round and pyramids are triangular . There is an musical instrument called a Triangle.Then there are pentagons and octogons. Googolgons too in some other universe perhaps?. Why do shapes matter? Well a square ball might not bounce as well and a triangular box wouldn't hold as much . I've seen round ice cube from trays that have round areas for the water but usually ice cubes are square. Never saw any that were triangular but I suppose they exist somewhere. A whole new area to ponder upon. Shapes. Do you have a favorite one?
