The use of new digital technologies in the classroom has become increasingly common and beneficial to the teaching and learning of mathematics. GeoGebra stands out among the possible software. It combines elements of geometry and algebra in a dynamic and interactive way, allowing students to explore mathematical concepts in a more practical and visual way, which makes it easier to understand and retain the content. One of the main advantages of Geogebra is the possibility of manipulating mathematical objects such as points, lines, curves and geometric figures. Students can move and modify these elements, immediately observing the effects of these changes on the graphical representation. This enables a deeper understanding of mathematical concepts and relationships, as well as allowing the investigation of various properties and specific cases, enriching the learning process. In this paper, we discuss the contributions of its use to the construction of definitions, conjectures and proofs in Plane Geometry.
