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. |

VIDEO: TI-Nspire CX Mini-Tutorial: Constructing an Angle Bisector
In this TI-Nspire CX tutorial, we go through the steps of constructing an Angle Bisector and measuring the distance from a point on the Bisector to the rays that define the angle. |
