Review for "Triangles semblables, angles et proportionnalités"

Activité3:Angles et proportionnalité

Global comment:

Review filed on 2010/10/10 07:04 by messaoudadouridj.

Cette activité est assez stimulante amène l'élève à faire appel à la déduction à partir d'une figure sur Cabri mettant en évidence la relation existante entre les angles d'un triangle et les cotés dans un rapport de similitude .Grâce à la manipulation de cette figure,l'élève est encouragé conjecturer et faire des liens entre plusieurs concepts.
This review is done without a trial in classroom.
