These pages were constructed with Geometer's Sketchpad 4 (see below). They are not organized at the moment, and the topics are quite miscellaneous. Perhaps more sketches and better organization will follow in time. Any links to the individual pages may change in the future.
Euclidean and/or Affine Plane Geometry
Spherical Geometry via Stereographic Projection
