Resumen de Programa TGP para la enseñanza de las transformaciones geométricas en el plano
José Fábrega, María del Carmen Morillo Balsera 
We present the methodology we used in the development of a program that classifies geometric transformations in the euclidean plane and calculates all the characteristic elements of' them or, vice versa, from these elements constructs the transformation matrix which calculates the image of' any point of the plane.
