Although it is a significant element for understanding conic curves, the latus rectum is rarely discussed in conventional textbooks, both at the high school and undergraduate levels. To address this gap, a qualitative and exploratory research was conducted, based on historical and bibliographic sources, with emphasis on the work of Apollonius of Perga and modern analytical geometry manuals. In addition to the theoretical foundation, this study proposes the graphical construction of the latus rectum using the GeoGebra software, aiming to enhance visualization and facilitate the teaching and learning process. The use of this technological tool seeks to make mathematical concepts more accessible, dynamic, and interactive, thus bridging theory and educational practice.ptAttribution-NonCommercial-NoDerivs 3.0 BrazilMatemática – EnsinoGeogebraLatus rectumGeometria analíticaMathematics teachingAnalytic geometryTrabalho de Conclusão de CursoCIENCIAS EXATAS E DA TERRA::MATEMATICA
