Euclid's Construction Exercises (Book I)
- John Golden
The propositions from Euclid's Elements, Book I, that form the basis of geometric constructions. As always, I'd recommend David Joyce's illustration of Euclid: http://aleph0.clarku.edu/~djoyce/java/elements/elements.html Another sketch just has the problems/propositions: http://www.geogebratube.org/material/show/id/50304 This sketch consists of some possible constructions to satisfy them. Both sketches have a reduced set of tools to simulate straightedge and compass constructions.
