Geometry ApplicationsTrianglesSegment 1: Geometry Basics. 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. Segment 2: Triangles. The properties of triangles are used to explain the frequent use of triangular trusses in many structures including the Eiffel Tower. In particular, isosceles and equilateral triangular trusses are explored. In addition, triangle postulates and similarity are explored and analyzed. Key concepts: triangles, isosceles triangles, equilateral triangles, congruent triangles, similar triangles and s-s-s postulate. Segment 3: Right Triangles. 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. Key concepts: right trian
