The subject of geometry was further enriched by the study of the intrinsic structure of geometric objects that originated with Euler and Gauss and led to the creation of topology and differential geometry.
A disciplina da xeometría foi posteriormente enriquecida polo estudo da estrutura intrínseca dos obxectos xeométricos iniciado por Euler e Gauss e que levou á creación da topoloxía e a xeometría diferencial.
