Triangle Art

More directly inspired by Simon Gregg’s musings, trying to think out a possible middle school mathart project. http://seekecho.blogspot.fr/2015/02/i-wrote-last-year-about-how-pythagoras.html I like the 1xroot(2) rectangle for this, because 2 stacked copies are similar to the original, which is nice with the subdivisions.
