Video Transcript: Geometry Applications: Triangles	Video Transcript: Geometry Applications: Triangles This is the transcript for the video of same title. Video contents: In this program we explore the properties of triangle. 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.	Applications of Triangles

Video Transcript: Geometry Applications: Triangles, Segment 2: Triangles	Video Transcript: Geometry Applications: Triangles, Segment 2: Triangles This is the transcript for the video of same title. Video contents: 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
