Closed Captioned Video: Geometry Applications: Triangles 
Closed Captioned Video: Geometry Applications: Triangles
In this program we explore the properties of triangle. We do this in the context of two realworld applications. In the first, we explore the triangular trusses in the Eiffel Tower and in the process learn about key properties of triangles. 
Definition of a Triangle and Applications of Triangles  
Closed Captioned Video: Geometry Applications: Triangles, 1 
Closed Captioned Video: Geometry Applications: Triangles, Segment 1: Introduction
The Bank of China building in Hong Kong is a dramatic example of triangular support. The notion of triangular trusses is introduced, along with the key concepts developed in the rest of the program.

Closed Captioned Video: Geometry Applications: Triangles, Segment 2: Triangles
The Eiffel Tower includes quite a number of exposed triangular trusses. The properties of triangles are used to explore and explain the frequent use of triangular trusses in many building. In particular, isosceles and equilateral triangular trusses are explored.

Closed Captioned Video: Geometry Applications: Triangles, Segment 3: Right Triangles
The ancient port city of Corinth in Greece allows us to explore the evolution of sailing. The shapes of sails went from rectangular to triangular. The use of righttriangleshaped sails changed the nature of sailing.
