20.) What is a geodesic dome?

A geodesic dome is "a sphere-like structure composed of a complex network of triangles." These triangles cause this structure to have a self-bracing framework that gives structural strength while using a smaller amount of material. "Geodesic" is a Latin word meaning "earth dividing." In a mathematical and architectural sense, a geodesic line is "the shortest distance between any two points on a sphere."

One of the most well-known geodesic domes is located in Orlando, FL. As a matter of fact, it is located at Disney World. This structure that I am referring to is the Epcot Center, as shown below.
