Defining Mathematical Properties of Three-Dimensional Shapes

Taught by Professor James Tanton, Ph.D.

Why learn about the properties of three-dimensional shapes? Consider this: inscribed over the entrance of Plato’s Academy were the words “Let no one ignorant of geometry enter my doors”. To ancient scholars, geometry was the gateway to knowledge. It’s core skills of logic and reasoning are essential to success in school, work, and many other aspects of life.

In this full lecture, we’ll study common mathematical properties of three-dimensional shapes such as cones, spheres, cylinders and pyramids.
