VIDEO: Geometry Applications: Angles and Planes, 3 |
VIDEO: Geometry Applications: Angles and Planes, Segment 3: PlanesIn the Canadian Rockies, the Burgess Shale fossils provide a window to prehistoric Earth. Fossil layers are folded into sedimentary rocks. And sedimentary rocks are examples of parallel planes. This segment uses the properties of planes to analyze fossils. |

VIDEO: Geometry Applications: Angles and Planes, 2 |
VIDEO: Geometry Applications: Angles and Planes, Segment 2: AnglesHimeji castle in Japan is a marvel of architecture and a startling example of geometry and military science. |
|
VIDEO: Geometry Applications: Angles and Planes, 1 |
VIDEO: Geometry Applications: Angles and Planes, Segment 1: IntroductionThe observatory in Arecibo, Puerto Rico provides astronomers insights into the structure of our solar system. Geometrically, the solar system relies on the plane known as the ecliptic. |
|
VIDEO: Geometry Applications: Angles and Planes |
VIDEO: Geometry Applications: Angles and PlanesIn this program we explore the properties of angles and planes. We do this in the context of two real-world applications. In the first, we explore Japan's Himeji Castle and in the process learn about different types of angles and how they're used in a defensive fortification. |

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. |
|
VIDEO: Geometry Applications: 3D Geometry, Triangular Prisms |
VIDEO: Geometry Applications: 3D Geometry, Triangular PrismsIn 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. |
|
VIDEO: Geometry Applications: 3D Geometry, Rectangular Prisms |
VIDEO: Geometry Applications: 3D Geometry, Rectangular PrismsIn 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, Pyramid Volume |
VIDEO: Geometry Applications: 3D Geometry, Pyramid VolumeIn 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, Antiprisms |
VIDEO: Geometry Applications: 3D Geometry, AntiprismsIn 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, 3 |
VIDEO: Geometry Applications: 3D Geometry, Segment 3: CylindersThe 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, 2 |
VIDEO: Geometry Applications: 3D Geometry, Segment 2: PyramidsRectangular 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. |
|
VIDEO: Geometry Applications: 3D Geometry, 1 |
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. |
|
VIDEO: Geometry Applications: 3D Geometry |
VIDEO: Geometry Applications: 3D GeometryIn 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. |
