Circles defined for a triangle
In Euclidean plane geometry, the van Lamoen circle is a special circle associated with any given triangle . It contains the circumcenters of the six triangles that are defined inside by its three medians. Specifically, let , , be the vertices of , and let be its centroid (the intersection of its three medians). Let , , and be the midpoints of the sidelines , , and , respectively. It turns out that the circumcenters of the six triangles , , , , , and lie on a common circle, which is the van Lamoen circle of . (Wikipedia).

Jean Delcourt, Lagrange et la géométrie : une théorie du contact
Jean Delcourt présente la conception de Lagrange du contact des courbes. Ecartant le modèle antérieur des courbes considérés comme des polygones à une infinité de côtés infiniment petits, il développe, dans la seconde partie de la Théorie des fonctions analytiques, une théorie du contact f
