  skos:definition """En géométrie, les cercles d’Archimède sont deux cercles de même aire construits à l’intérieur d’un arbelos. Ils apparaissent dans le Livre des lemmes, attribué à l’époque médiévale au mathématicien grec Archimède, d’où leur nom.

An arbelos is determined by three collinear points A, B, and C, and is the curvilinear triangular region between the three semicircles that have AB, BC, and AC as their diameters. If the arbelos is partitioned into two smaller regions by a line segment through the middle point of A, B, and C, perpendicular to line ABC, then each of the two twin circles lies within one of these two regions, tangent to its two semicircular sides and to the splitting segment.
