Closed Captioned Video: Circumscribing a CircleTriangle
In this TI Nspire tutorial, the Geometry window is used to circumscribe a circle about a triangle. This video supports the TINspire Clickpad and Touchpad. This MiniTutorial Video includes a worksheet. .


Geometric Constructions with Triangles


Closed Captioned Video: Geometry Applications: Circles
In this program we explore the properties of circles. We do this in the context of two realworld applications. In the first, we look at the design of the Roman Coliseum and explore how circular shapes could have been used to design this elliptical structure.

Closed Captioned Video: Geometry Applications: Circles, Segment 1: The Basics of Circles.
We visit Chaco Canyon in New Mexico to explore the circular kivas and in the process discover how circular buildings have been used to study the heavens.

Closed Captioned Video: Geometry Applications: Circles, Segment 2: Circles and Arcs.
The Roman Coliseum is a large elliptical structure. Yet, the Romans likely used circular arcs to build it. This segment explores the properties of circles and shows how arcs can be used to create elliptical shapes.

Closed Captioned Video: Geometry Applications: Circles, Segment 3: Chords and Inscribed Angles
The Roman Pantheon is a domed structure that shows a keen awareness of the position of the sun throughout the year. The source of light from the top of the dome allows for the exploration of chords, inscribed angles, central angles, and intercepted arcs.
