The 11 pages that link to Euler line, each with the reason it gives.

• CircumcenterRelated: The circumcenter is one of the triangle centers aligned on this line.

• OrthocenterRelated: The orthocenter lies on this line with two other major triangle centers.

• Triangle geometryRelated: It links three fundamental centers in a fixed ratio and alignment.

• Nine-point circleRelated: The nine-point center lies on this line, midway between circumcenter and orthocenter.

• Euler's inequalityRelated: It connects the circumcenter to another central feature of triangle geometry.

• Simson lineCompared with: It is another classical triangle line, but it links centers rather than projected feet.

• Triangle centersRelated: It captures a relationship that becomes degenerate when these centers coincide.

• Feuerbach's theoremRelated: Its circumcenter–orthocenter segment locates the nine-point center.

• Monge's theoremCompared with: It is another classical line through three geometrically defined points, arising from a different configuration.

• Incenter–excenter lemmaCompared with: It links other familiar centers; the incenter generally does not lie on it.

• Reuschle's theoremRelated: It is a central alignment result in the same geometry of triangle centers.
