Closed Captioned Video: Geometry Applications: Circles

Description

In this program we explore the properties of circles. We do this in the context of two real-world 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.

Description

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. A Video Transcript is available for this tutorial. Note: The download is Media4Math's guide to closed captioned videos.

Closed Captioned Video: Geometry Applications: Circles, Segment 2: Circles and Arcs.

Description

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. A Video Transcript is available for this tutorial. Note: The download is Media4Math's guide to closed captioned videos.

Closed Captioned Video: Geometry Applications: Circles, Segment 3: Chords and Inscribed Angles

Description

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. A Video Transcript is available for this tutorial.
