It uses the GeoGebra as a tool for building a step by step procedure to convince students of the veracity of results that have simple statements, but not trivial proofs. The following theorems were worked: Morley's Theorem, Hipparchus Theorem, Stewart's Theorem, Menelaus Theorem and 9-Point Circle Theorem. Demonstrations are held strictly in the traditional way, and in parallel it is used the GeoGebra software, thus giving a playful view of the statements. It is understood that this approach will be more attractive, enabling a better understanding of the theorems by students. The work culminates with the application of a motivational test to a class of basic education after a class in which they worked the 9-Point Circle using GeoGebra / Este trabalho tem a inten??o de apresentar o softwarede Geometria Din?micaGeoGebra ao aluno do Ensino B?sico. Utiliza-se o GeoGebra como ferramenta para a constru??o din?mica de um passo-a-passo para convencer os alunos da veracidade de resultados que possuem enunciados simples, mas demonstra??es n?o triviais. Foram trabalhados os seguintes teoremas: Teorema de Morley, Teorema de Hiparco, Teorema de Stewart, Teorema de Menelau e Teorema do C?rculo de 9 Pontos. As demonstra??es s?o realizadas rigorosamente, da forma tradicional, e em paralelo ? feito o uso do softwareGeoGebra, dando assim uma vis?o l?dica das demonstra??es. Entende-se que esta abordagem ser? mais atrativa, possibilitando uma melhor compreens?o dos teoremas pelos alunos. O trabalho culmina com a aplica??o de um teste motivacional a uma turma do Ensino B?sico ap?s uma aula em que se trabalhou o Teorema do C?rculo dos 9 Pontos utilizando-se o GeoGebra
