Geometry Automated Theorem Provers have now what may be considered a long story. Since the early attempts, linked to Artificial Intelligence, synthetic provers based on inference rules and using forward chaining reasoning are considered the more suited for education. Using an appropriated set of rules and using forward chaining they can more easily mimic the expected behaviour of a student when developing a proof. We describe an implementation of the geometry deductive database method, discussing its merits, and demerits when an application in education is concerned.
