### Closed Captioned Video: Geometry Applications: 3D Geometry

Closed Captioned Video: Geometry Applications: 3D Geometry

In this program we explore the properties of three-dimensional figures. We do this in the context of two real-world applications. In the first, we look at the three-dimensional structure of Mayan pyramids.

### Closed Captioned Video: Geometry Applications: 3D Geometry, 1

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 three-dimensional 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, 3

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

In this program we explore the properties of three-dimensional figures. We do this in the context of two real-world applications. In the first, we look at the three-dimensional structure of Mayan pyramids. These stair-step structures provide a unique opportunity to also explore sequences and series.

### VIDEO: Geometry Applications: 3D Geometry, Antiprisms

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

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 hands-on 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.

### VIDEO: Geometry Applications: 3D Geometry, Triangular Prisms

VIDEO: Geometry Applications: 3D Geometry, Triangular Prisms

In this video students study a real-world application of triangular prisms: The Flat Iron Building in New York City. This building is an ideal example of a real-world prism and also provides a tie-in 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.
