Some triangles have names on them: Pascal's Triangle, isosceles triangle, a carpenter's triangle; some have famous results about themPythagorean Theorem, Heron's formula; and some form the backbone of nearly all loadbearing manmade structures: Trusses (okay, ditch the Bermuda Triangle and love triangles). There are even spherical triangles. Your task: Your task for this discussion activity is to research and write a summary about some historical, important, or practical aspect of triangles. Your summary can be entertaining, but should cover something nontrivial, like where are triangles in use and how do we use them? Your contribution must be instructive to the class. Write a concise summary with a minimum of \"fluff\". A contribution should be in the neighborhood of 250400 words. This is not a term paper, but it should be crisp, with no puffery. Document your sources in APA style so that your instructor can review your source(s)
