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 This sketch just has the problems/propositions. Another sketch has some solutions: http://www.geogebratube.org/material/show/id/50701. Both sketches have a reduced set of tools to simulate straightedge and compass constructions.
