A Little Knowledge Background

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 load-bearing man-made 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 summary of some historical, important, or practical aspect of triangles. Your summary can be entertaining, but should cover something non-trivial, like where are triangles in use and how do we use them? Your contribution must be instructive to the class. Youmustpost your initial responsebeforeyou can view your peers'.

Write concise summary with a minimum of "fluff." A contribution should be in the neighborhood of 250- 400 words. This isnot a term paper, but it should be crisp, with no puffery.
