Contribuições do software Geogebra para o ensino e ensino e aprendizagem de congruências e semelhanças de triângulo no 1° ano do ensino médio

Abstract

This study presents qualitative, descriptive field research aimed at analyzing the contributions of the GeoGebra software to the teaching of triangle congruence and similarity, applied at the Federal Institute of Piauí - São Raimundo Nonato Campus, with a 1st-year High School class. The research problem is: "How does the GeoGebra software contribute to the teaching and learning process in the context of plane geometry, specifically regarding the content of triangle congruence and similarity in a 1st-year high school class?" The theoretical framework was based on the following authors: Lima (2009), Almeida and Valente (2012), Behrens (2000), and Silveira and Bazzo (2009). To achieve the research objectives, the workshop was divided into three moments. The first moment was dedicated to the students' immersion and familiarization with the GeoGebra software. The second moment involved the beginning of the explanation of the GeoGebra software tools. The third moment focused on problemsolving with the assistance of the software. Finally, data verification was performed through systematic observation and questionnaire analysis. Consequently, this research highlighted
