Resumen
In a PhD research context, we present the analysis of the three episodes in the observation of a teacher in third cycle of primary education when teaching geometry. Based on the analytical model about mathematics teachers' specialised knowledge (MTSK) knowledge, we analyse the knowledge of non-explicit content in the concepts of straight line, ray and segment shown by the teacher and the consequences it has in the classroom. We show how epistemological foundations of the knowledge about these concepts, despite being implicit, generates in the teacher's explicit knowledge obstacles and inaccuracies that she transmits to her students.
