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

Closed Captioned Video: Geometry Applications: Angles and Planes

In 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.

## Google Earth Voyager Story: The Geometry of Castles

Google Earth Voyager Story: The Geometry of Castles

During Medieval times, castles were fortresses, mini-cities where the royalty lived, and symbols of power. Most castles were tall, imposing structures. But why were they so tall? Was it just for symbolic reasons, to allow a king to show his center of power and influence?
