How this entity was disambiguated
This entity first appeared as the object of triple T21610208 — resolving that mention is where its identity was fixed. The disambiguator weighed these candidate entities and picked the highlighted one (or “None”, minting a new entity). This is how homonymy is resolved: the same surface form can point to different entities.

Target entity: Steiner chain Context triple: [Jakob Steiner, notableWork, Steiner chain]
-
A.
Tusi couple
The Tusi couple is a geometric device from medieval Islamic astronomy that generates linear motion from the sum of two circular motions, later influencing Copernican models of planetary motion.
-
B.
Soddy circle
A Soddy circle is one of the circles in a configuration of four mutually tangent circles, central to the geometric problem described by Descartes' circle theorem.
-
C.
Poncelet polygon
A Poncelet polygon is a cyclic polygon that can be simultaneously inscribed in one conic and circumscribed about another, illustrating Poncelet’s porism in projective geometry.
-
D.
Miquel circle
The Miquel circle is a notable circle in geometry that passes through the three points where the circumcircles of the triangles formed by choosing three vertices of a quadrilateral intersect.
-
E.
Rowland circle geometry
Rowland circle geometry is an optical configuration used in spectrometers where a concave diffraction grating and its focal curve lie on a common circle to achieve high-resolution wavelength dispersion.
- F. None of above. chosen
- G. Unsure - the case is ambiguous/there is not enough information to decide.
