Concentricité

La concentricité est la propriété des objets qui sont concentriques, c'est-à-dire qui partagent le même centre. En géométrie, on parle par exemple de cercles concentriques pour désigner des cercles qui partagent le même centre sans avoir nécessairement le même diamètre[1]. Comme d'autres exemples on peut citer, les polygones réguliers[2], les polyèdres réguliers[3] et les sphères[4].
