Closed Captioned Video: Geometry Applications: 3D Geometry 
Closed Captioned Video: Geometry Applications: 3D Geometry
In this program we explore the properties of threedimensional figures. We do this in the context of two realworld applications. In the first, we look at the threedimensional structure of Mayan pyramids. 
3Dimensional Figures

Closed Captioned Video: Geometry Applications: 3D Geometry, Segment 1: Introduction.
We visit ancient Greece to learn about the Platonic Solids. This provides an introduction to the more general topic of threedimensional figures.

Closed Captioned Video: Geometry Applications: 3D Geometry, Segment 2: Pyramids
Rectangular Prisms. Mayan pyramids are essentially stacks of rectangular prisms. The volume of each successive level is a percentage decrease of its lower neighbor. This introduces the notion of a geometric sequence and series, including an infinite series.

Closed Captioned Video: Geometry Applications: 3D Geometry, Segment 3: Cylinders
The Shanghai Tower in China is a stack of cylindrical shapes, where each successive layer is a percentage decrease of its lower neighbor. As with the previous section, this introduces the notion of a geometric sequence and series.

VIDEO: Geometry Applications: 3D Geometry, Antiprisms
In this video students learn the basics of antiprisms, in the context of New York’s Freedom Tower, which has an antiprism design. They learn the properties of antiprisms, with the focus on those with a square base.

VIDEO: Geometry Applications: 3D Geometry, Pyramid Volume
In this video, students see a derivation of the formula for the volume of a pyramid. This involves a handson activity using unit cubes, along with analysis, and a detailed algebraic derivation.

VIDEO: Geometry Applications: 3D Geometry, Rectangular Prisms
In this video students learn the basics of rectangular prisms, in the context of a New York residential tower: 432 Park Avenue. 
Rectangular Prisms  
VIDEO: Geometry Applications: 3D Geometry, Triangular Prisms 
VIDEO: Geometry Applications: 3D Geometry, Triangular Prisms
In this video students study a realworld application of triangular prisms: The Flat Iron Building in New York City. This building is an ideal example of a realworld prism and also provides a tiein to right triangle geometry. 
Triangular Prisms  
VIDEO: Geometry Applications: 3D Geometry, What Are Prisms? 
VIDEO: Geometry Applications: 3D Geometry, What Are Prisms?
In this video students learn the basics of prisms and anti prisms. They learn the properties of triangular prisms, rectangular prisms, triangular antiprisms, and rectangular antiprisms.
