This article presents a method for approximating Pi using similar triangles that was inspired by the authors work with middle school teachers. The method relies on a repeated application of a geometric construction that allows us to inscribe regular polygons inside a unit circle with arbitrarily large number of sides.

On a trip to Hungary, students and teacher become intrigued by a problem and work out several solutions Online extra: http://www.nctm.org/uploadedFiles/Journals_and_Books/MT/articles/2011-Vol_105/Extras-Vol_105/mt2011-09-150z1.pdf NOTE: In the print version of Delving Deeper for MT September 2011, a production error resulted in incorrect labels in figure 2. The labels should be the same as those in figure 1. This online version is correct.
