Review for "Théorème de Thalès"

Après utilisation en classe

Global comment:

Review filed on 2012/09/26 13:38 by bclerc.

Cette activité va me servir à introduire le théorème de Thalés complet, au niveau troisième, en vidéo projection. Les pré-requis sont la notion de proportionnalité, la connaissance de la proportionnalité des longueurs dans un triangle, les propriétés de la symétrie centrale.
This review is done without a trial in classroom.
