Interior (topology)

Interior topology is all about shapes and spaces. Imagine a house. The walls of the house create a space; they make a container that holds the things in the house. That space created by the walls is called the interior. If you look inside the house, you can see different shapes and spaces. Those shapes and spaces define the interior topology of the house. In other words, the interior topology of a house defines how the shapes and spaces inside the house are arranged.
