I have drawn the incircles of triangles which were generated through a delaunay triangulation but lost the original delaunay mesh. Is it possible to invert the process and draw the triangles back from this list of circles?
Many thanks,
Arthur

If there is a way to find a line mutually tangent to a pair of circles, then drawing tangents to pairs of neighbouring circles would produce the mesh.
If the circles X and Y have radii of x and y and a distance between them of z then, because the radii meeting the tangent are parallel, the angles between the radii and the line connecting the centres of the circles are equal, and given by cos((x+y)/z).
