Transformational Geometry Links

Wilson Strother's geometry pages[[1] (] organized around Klein's definition of geometry and various groups of transformation.  
  • Look, for example, at the pages on Affine Geometry [[2] (]

Are there good sequences of problem solving materials that support the use of transformational reasoning?

  • Consider the three volume work of Yaglom: Geometric Transformations I, II, III, IV which are problems, and solutions, designed for advanced high school students. I recommend them - particularly when used with a companion dynamic geometry program.
