This article presents an example of the use of technology, specifically GeoGebra®, to introduce Book I of Euclid’s Elements (which ends with the Pythagorean Theorem and its converse) into the teaching of mathematics. This dynamic geometry software allows new approaches to Euclid's proofs, enabling students to have access to step-by- step constructed images, rather than just a static final image as seen in a book or a PDF. This facilitates a better understanding of the mathematical contents, as well as the argumentations used in each step of the proofs. This is an ongoing work; the ultimate goal of which is to have all the proofs from Euclid’s Elements Book I accessible on GeoGebra for free use.
