# Trigonometry Discussion

**Question description**

Some 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.

Write 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.

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 non-trivial, like where are triangles in use and how do we use them? Your contribution must be instructive to the class.
