The Euclid Project is the second geometry workbook in this series developed by Dr. Robert E. Mason IV on constructivist learning of geometry. This non-traditional approach to learning geometry invites students to ponder, question, speculate, and discovery for themselves the theorems, and definitions of Euclidean Geometry. Students's use Geometer's Sketchpad as their electronic "tabula rasa" on which they illustrate geometric proofs.
