The 12 pages that link to Jakob Steiner, each with the reason it gives.

• Isoperimetric inequalityRelated: His geometric arguments helped establish the circle’s optimality, though required an existence argument.

• Complete quadrilateralRelated: Steiner developed influential synthetic geometry around configurations including quadrilaterals.

• Isoperimetric problemRelated: His geometric arguments strongly influenced proofs that the circle solves the planar problem.

• Jean-Victor PonceletRelated: Steiner developed a synthetic geometric tradition alongside Poncelet’s influence.

• Miquel pointRelated: Steiner's circle geometry provides historical context for the theorem's development.

• Poncelet–Steiner theoremRelated: Steiner gave the classical proof that the fixed circle and its center suffice.

• Six circles theoremRelated: Steiner’s synthetic geometry provides historical context for classical circle theorems.

• Gilbert–Pollak conjectureRelated: The conjecture concerns the network optimization problem bearing his name.

• Seven circles theoremRelated: Steiner helped shape the synthetic geometry tradition in which circle configurations were studied.
