In this paper we analyse, with a perspective of mathematics education, a videotape showing two 9 th grade students cooperating to write instructions in order that other students could construct a circle tangent to the sides of a given angle. Our aim is to understand how they articulate with their geometric knowledge different semiotics means (mainly words and figures, freehand or drawn with usual instruments) in an evolving semiotic bundle so that the solution as well as the geometric knowledge progress. We also try to identify the way each student contributes to develop the semiotic bundle and how each contribution evolves in the course of their solving.Dans cet article, nous analysons d’un point de vue de didactique des mathématiques la v...
