Lesson 5 Summary
Many types of bridges were built by First Nations peoples for a variety of reasons. Search the Internet for “Living Landscapes + The Social Landscape of Bridges.” Lightly read the article “The Social Landscape of Bridges” and check out the different bridges that were built. Pay attention to the types of material used.
The National Film Board’s 1965 film High Steel celebrates the skill and bravery of the steel workers from the Kahnawake Reserve near Montreal. For decades, people from this community worked on the steel structures that give New York its skyline.
Search the Internet for “National Film Board of Canada High Steel,” and watch the video.
Iron workers, whether erecting bridges or buildings, depend on the design of these structures for their safety. These designs are, in part, an application of the mathematics you studied in this lesson.
In this lesson you investigated practical applications of right–angle trigonometry and the Pythagorean theorem. These applications involved more than one right triangle in three dimensions.
