Euclid in pictures

Oliver Byrne produced a version of 'Elements of Euclid' in 1847 with colour used to emphasise relationships and very little text

this is proposition (theorem) 43 from Euclid Book 1











this theorem was intended to establish how to transform one parallelogram to another, of equal area and with the same angles





students could be asked to provide the words for this sequence of diagrams








a very helpful compendium of the works of 'Euclid' is provided by David E Joyce at Clark University in Worcester, MA
