O conteúdo desenvolvido nas atividades foi o de Geometria Plana com ênfase em polígonos e quadriláteros notáveis. O artigo tece também reflexões sobre como a tecnologia pode potencializar e auxiliar o professor no ensino da Geometria. As atividades desenvolvidas tiveram o aporte teórico no modelo de pensamento geométrico de Van Hiele e a utilização dos recursos tecnológicos em sala de aula está fundamentada em uma perspectiva teórica conforme os autores estudados. A reflexão aqui apresentada é fruto de um estudo qualitativo, no qual se utilizou o <em>software</em> GeoGebra como recurso tecnológico. Como intuito de averiguar o desenvolvimento de competências e habilidades geométricas foi realizado com a turma durante o experimento de ensino um pré-teste e um pós-teste. A título de conclusão infere-se que o experimento de ensino possibilitou aos estudantes avançar progressivamente na construção de conhecimentos sobre polígonos e quadriláteros notáveis; e ao professor-pesquisador, refletir sobre a qualidade do ensino da geometria quando se integram recursos tecnológicos ao fazer docente.</p><p><strong>Palavras-chave: </strong>Geometria.

with high school students. The content developed in the activities was that of Flat Geometry with emphasis on polygons and remarkable quadrilaterals. The article also discusses how technology can enhance and assist teachers in the teaching of Geometry. The activities developed had the theoretical contribution in the Van Hiele geometric thinking model and the use of technological resources in the classroom is based on a theoretical perspective according to the authors studied. The reflection presented here is the result of a qualitative study, in which GeoGebra software was used as the technological resource. In order to ascertain the development of geometric skills and abilities, a pre-test and a post-test were performed with the class during the teaching experiment. As a conclusion, it is inferred that the teaching experiment made it possible for the students to progress progressively in the construction of knowledge about remarkable polygons and quadrilaterals; and the teacher-researcher, reflect on the quality of geometry teaching when integrating technological resources when making teachers.</span></pre><p class="MsoNormal" style="margin-bottom: .0001pt; text-align: justify; line-height: normal; tab-stops: list -18.0pt;"><strong style="mso-bidi-font-weight: normal;"><span style="font-size: 12.0pt; font-family: ’Times New Roman’,’serif’; mso-fareast-font-family: Calibri; color: black; mso-themecolor: text1; mso-ansi-language: EN-US;" lang="EN-US"> </span></strong></p><p class="MsoNormal" style="margin-bottom: .0001pt; text-align: justify; line-height: normal; tab-stops: list -18.0pt;"><strong style="mso-bidi-font-weight: normal;"><span style="font-size: 12.0pt; font-family: ’Times New Roman’,’serif’; mso-fareast-font-family: Calibri; color: black; mso-themecolor: text1; mso-ansi-language: EN-US;" lang="EN-US">Keywords: </span></strong><span style="font-size: 12.0pt; font-family: ’Times New Roman’,’serif’; mso-fareast-font-family: Calibri; color: black; mso-themecolor: text1; mso-ansi-language: EN-US;" lang="EN-US">Geometry.
