triangles have names on them: Pascal’s Triangle, isosceles
triangle, a carpenter’s triangle; some have famous results about
them—Pythagorean 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.
a concise summary with a minimum of “fluff”. A contribution should be in the
neighborhood of 250-400 words. This is not a term paper, but it should be
crisp, with no puffery.
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 non-trivial, like where are
triangles in use and how do we use them? Your contribution must be
instructive to the class.
