Dear Geometers,

Yesterday we talked about geometric solids. We discussed the properties of these different solids to compare and contrast them. Today, we’ll talk about a specific class of geometric solids. As we’re studying them, be thinking about the trait that they all share. Just as amphibians, reptiles, mammals, birds, and fish belong to their classes based on specifc traits, humans also classify geometric solids by specific traits.

The difference between organisms and geometric figures is that one exists in the real world and one mostly exists in the world of ideas. We can find real world approximations for cylinders, spheres, and other geometric solids, but they are mostly ideas that exist based on traits that humans agree on. For that reason, they have a certain, magical, power.

Sincerely,

Mr. H
