The 27 pages that link to Projective plane, each with the reason it gives.

• Homogeneous coordinatesNarrower topic: Each projective point is represented by a scale-equivalent triple of homogeneous coordinates.

• Pascal's theoremNarrower topic: The theorem's intersections remain defined when opposite sides are parallel.

• Complete quadrilateralNarrower topic: The configuration’s incidence relations hold naturally in projective geometry.

• Pappus's hexagon theoremNarrower topic: This is the setting that guarantees every pair of opposite sides has an intersection.

• Sylvester–Gallai theoremNarrower topic: Projective transformations provide another way to analyze point-line incidence configurations.

• Wedderburn's little theoremNarrower topic: The theorem restricts algebraic coordinate systems available for finite examples.

• Cayley–Bacharach theoremNarrower topic: The theorem’s clean intersection statement is naturally formulated for projective plane curves.

• Desargues's theoremNarrower topic: The theorem holds in this setting, including intersections at infinity.

• Bruck–Ryser–Chowla theoremNarrower topic: The theorem’s projective-plane condition rules out certain orders through a sum-of-squares equation.

• Thomsen's theoremNarrower topic: The theorem depends on incidence alone, without requiring distances or angles.
