By Nanette Seago, Patrick Callahan, Mark Driscoll, Jennifer Jacobs, Johannah Nikula

geometrictransformation

 This first-of-its-kind illustrated and laminated guide helps both secondary school teachers and students understand geometric transformation, similarity, and congruence.

Developed by the Learning and Teaching Geometry Project, this resource features:

  • Definitions of important terms
  • Color coordination of key phases
  • Diagrams with examples and non-examples
  • Examples of precise and imprecise language
  • Properties for translation, rotation, reflection, dilation, congruence, and similarity
