Trigonometria utilizando o software cabri géomètre

Abstract

The article has objective to present a report of a pedagogyc experiene in wich will be taught trigonometry using the cabri géomètre software. This experience has suport in a proposition wich objectives are leting the student to: i) refer the triangle’s likeness contents with the trigonometrics quocient contents, resulted and aplicated to problems situations of real kinds and recreative and ii) explain orally and writting these same quocient using the cabri géomètre sftware. This proposition is inserted in the context, of a research developed by components of the investigation Nucleus in Mathematics Education – (NIEMAT – Núcleo de Investigação em Educação Matemática), from Campus Avançado de Jataí/Universidade Federal de Goiás, in Jataí, that seeks understanding the geometric arguments, developed by primary school students, in two diferente classes situations: one in wich the responsable maths teacher presents the geometry lessons, and another in wich the probationers are the ones, licensed in maths, assume the regency of these classes.
