This is the beginning in a series of expositions based on Euclid using the Geometer's Sketchpad as an illustrator. It relies on the famous translation work of John Playfair.
Part I begins with the definitions propounded by Euclid. I have provided for interactive viewing which requires at least a demonstration copy of Geometer's Sketchpad 3.0. You can obtain the demo version from Key Curriculum press in either 'Macintosh' or 'Windows' versions.
