## Closed Captioned Video: Geometry Applications: Angles and Planes |
## Closed Captioned 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. |

## Closed Captioned 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. |
