VIDEO: Geometry Applications: Triangles	VIDEO: Geometry Applications: Triangles In this program we explore the properties of triangles. We do this in the context of two real-world applications. In the first, we explore the triangular trusses in the Eiffel Tower and in the process learn about key properties of triangles. In the second application, we look at right-triangle-shaped sails on sail boat and why these are the ideal shape for efficient sailing.	Definition of a Triangle and Applications of Triangles
VIDEO: Geometry Applications: Triangles, 1	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.	Definition of a Triangle and Applications of Triangles
VIDEO: Geometry Applications: Triangles, 2	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. In addition triangle postulates and similarity are explored and analyzed.	Applications of Triangles
VIDEO: Geometry Applications: Triangles, 3	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 right-triangle-shaped sails changed the nature of sailing. Becoming less reliant on oarsmen and being able to sail under nearly any wind conditions, the sailboat made the conquest of the seas possible. We explore the properties of right triangles that make such sails ideal.	Applications of Triangles and Definition of a Triangle
