With program support provided by Math for America The first is perhaps the best known of all. 2.3 SIMILARITY AND THE PYTHAGOREAN THEOREM Of the many important applications of similarity, there are two that we shall need on many occasions in the future. The case of a polygon containing h polygonal holes is discussed in Exercise 2.5.1. Send questions or comments to: Suzanne Alejandre and Jim King Try to prove Theorem 2.2.3 algebraically using Theorem 2.2.2. IAS/Park City Mathematics Institute is an outreach program of the Institute for Advanced Study, 1 Einstein Drive, Princeton, NJ 08540 © 2001 - 2018 Park City Mathematics Institute A few of the resources that were looked at include:A Euclidean Geometry course using GSP: Īn article addressing the "big picture" discussion we've been having: Solution 1 (Bash) Solution 2 (Using 3-4-5) We see looks like the legs of a right triangle with a multiplication factor of 111. The group began working on a template for overarchingquestions in a geometry class. One of the angles of a right triangle is always equal to 90 degrees. The other group is working on a constructivist approach to Geometry using GSP (andmaybe other software). In mathematics, the Pythagorean theorem or Pythagorass theorem is a statement about the sides of a right triangle. Some of these ideas are coming from the Looking forPythagoras unit in CMP. ic arrangement delivered an elegant proof to the Pythagorean Theorem. Two of the members of thegroup are working on developing pages in Sketchpad that is the preperatory workleading up to the proofs. concept in 2D and 3D using dynamic software like Geometers-Sketchpad and Cabri-II. Two ofthe members are working on several proofs of the theorem. The middle school partnership in the geometry working group is working on developinggraphical representations of the Pythagorean Theorem in Geometer's Sketchpad. Compare/contrast different geometry software ( Cabri, GSP, Cinderella, Geogebra, etc.)Ĭontinued working in smaller groups of projects.Using Sketchpad to build nets for polyhedra.Relationship between perimeter and area.Spent some time brainstorming different projects possibilities. Used Sketchpad to explore and create different conics (parabolas, ellipses,and hyperbolas) using loci. Heshowed everyone much of the functionality, and talked about the broad view ofconstructions based on paper folding, compass/ruler, and technology. Investigating Geometry: July 7 - 11, 2008 Investigating Geometry Summary Monday - Friday, July 7 - 11, 2008Īrt spent the one hour going through through an overview of The Geometer's Sketchpad®.
