Trigonometry 1: (Right-angled Triangle)

Shape and Space Powerpoint Presentation

Trigonometry 1: (Right-angled Triangle)

A top quality presentation on the trigonometry of right-angled triangles. An unusual approach is taken at the start. The sequence auto-runs and tries to get the students to figure out how the height of the Eiffel Tower can be obtained without actually climbing it. Lots of cultural and historical aspects discussed as well as early applications. There's lots in this including: naming angles, explanations based on similar triangles, mnemonics, finding unknown sides/angles, angles of elevation/depression. A variety of problems set in a real world contexts with some nice graphics used throughout. Includes a slide on how the ratios got their names. Worksheets included.
