Geometric inversion, Mathematic programAbstract
The Senegalese Mathematics program of 2006 (current program) invites the teacher to give examples of transformations not preserve the barycentre in Terminal S1 and S3. This is why we consider it necessary to provide teacher with a lesson on geometric inversion. In this article, we will on the one hand experiment and analyze activities aimed at introducing geometric inversion in Terminale S1 class. On the other hand, we will conduct a survey of teachers to get an idea of the place occupied by distorting transformations in the teaching of mathematics in Senegal.
