Software Aids to Learning Elementary Geometry

Emma is taking Geometry, so I've collected and even produced some software tools to help high school Geometry students.

• Jeff Week's sterling Topology and Geometry Software
• Some explorations, requiring Java enabled web browser and/or Geometer's Sketchpad:
  • Constructing a Triangle, Given Three Sides
  • The Euler Segment of a Triangle
  • The 9 Point Circle of a Triangle
  • Constructing a Triangle, Given Two Angles and a Side, Not Between Them.
• The Geometer's Sketchpad
• Jürgen Richter-Gebert & Ulrich Kortenkamp's Cinderella
