Closed Captioned Video: Geometry Applications: 3D Geometry |
DescriptionIn 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. |

Closed Captioned Video: Geometry Applications: 3D Geometry, Segment 1: Introduction. |
DescriptionWe visit ancient Greece to learn about the Platonic Solids. This provides an introduction to the more general topic of three-dimensional figures. This video includes a video transcript: |

Closed Captioned Video: Geometry Applications: 3D Geometry, Segment 2: Pyramids |
DescriptionRectangular 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. A Video Transcript is available for this tutorial. |

Closed Captioned Video: Geometry Applications: 3D Geometry, Segment 3: Cylinders |
DescriptionThe 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. A Video Transcript is available for this tutorial. |
