Sym_cetrale

constructions

Etape2.2

- Fais varier le curseur 'animation' pour obtenir l'image de la figure 
  par la symétrie orthogonale proposée

- Coche 'Constructions' pour voir les constructions à effectuer 
  pour déterminer l'image d'un point par la symétrie orthogonale


- Tu peux modifier l'emplacement de chaque point pour obtenir 
  d'autres figures mais également modifier la position de l'axe de symétrie
