“How do we classify geometric objects with flat faces?”
Think of an object in three dimensions. Any object. You can probably come up with a wide array of diverse and seemingly unending chaotic shapes. But in geometry, we need to organize everything into patterns with special properties. So since we have already started with three dimensional objects, let’s go classify the simplest possible three-dimensional objects. But what exactly are they? Well, let’s think about it. We know that two dimensional objects are simply flat faces. So what if we took many of those flat faces and strung them together in an organized manner? This is the primary principle behind polyhedrons. Polyhedrons are three dimensional objects made completely out of two dimensional faces, with no opening. Did you know that every day objects such as cubes and pyramids are polyhedra?
