An interactive Web-based exploration designed to facilitate the teaching of triangle concurrency, both as an integral part of a geometry curriculum and as enrichment material. These pages can be used by individual students as a computer exploration, as classroom demonstration material, or as an alternative to a more traditional investigation of triangle congruency topics. Includes notes to students and teachers, and instructions for using the Geometer's Sketchpad in the activities. A final project created for Math 5337, Technology in the Geometry Classroom, at the Geometry Center, University of Minnesota. Alejandre A Math Forum Web Unit.
Students studying polyhedra enjoy seeing the structures as they occur in the real world.
Alejandre A Math Forum Web Unit. Includes some background on circles in Islamic cultures, and an activity exploring the geometry involved in some circle designs. Links to related pentomino and Fibonacci sites on the Web and a teacher lesson plan are provided. Each module offers interactive Java components and additional references. Part of the Chickscope project at the Beckman Institute.
