Reasoning by Contradiction in Dynamic Geometry (Razonamiento por contradicción en geometría dinámica)
This paper addresses contributions that dynamic geometry systems (DGSs) may give in reasoning by contradiction in geometry. We present analyses of three excerpts of students’ work and use the notion of pseudo object, elaborated from previous research, to show some specificities of DGS in constructin...
