    en.wikipedia.org/wiki/Lists_of_uniform_tilings...

    Special cases are right triangles (p q 2). Uniform solutions are constructed by a single generator point with 7 positions within the fundamental triangle, the 3 corners, along the 3 edges, and the triangle interior. All vertices exist at the generator, or a reflected copy of it. Edges exist between a generator point and its image across a mirror.

    Forum Geometricorum: A Journal on Classical Euclidean Geometry was a peer-reviewed open-access academic journal that specialized in mathematical research papers on Euclidean geometry. [ 1 ] Founded in 2001, it was published by Florida Atlantic University and was indexed by Mathematical Reviews [ 2 ] and Zentralblatt MATH . [ 3 ]

  4. Euclidean geometry - Wikipedia

    en.wikipedia.org/wiki/Euclidean_geometry

    Euclidean geometry is a mathematical system attributed to ancient Greek mathematician Euclid, which he described in his textbook on geometry, Elements. Euclid's approach consists in assuming a small set of intuitively appealing axioms (postulates) and deducing many other propositions ( theorems ) from these.

  5. Tarski's axioms - Wikipedia

    en.wikipedia.org/wiki/Tarski's_axioms

    Suitable changes in these axioms yield axiom sets for Euclidean geometry for dimensions 0, 1, and greater than 2 (Tarski and Givant 1999: Axioms 8 (1), 8 (n), 9 (0), 9 (1), 9 (n)). Note that solid geometry requires no new axioms, unlike the case with Hilbert's axioms. Moreover, Lower Dimension for n dimensions is simply the negation of Upper ...

  6. Uniform tiling - Wikipedia

    en.wikipedia.org/wiki/Uniform_tiling

    In geometry, a uniform tiling is a tessellation of the plane by regular polygon faces with the restriction of being vertex-transitive.. Uniform tilings can exist in both the Euclidean plane and hyperbolic plane.

  7. Ceva's theorem - Wikipedia

    en.wikipedia.org/wiki/Ceva's_theorem

    This point is the foot of a cevian that goes from the vertex opposite the k-face, in a (k + 1)-face that contains it, through the point already defined on this (k + 1)-face. Each of these points divides the face on which it lies into lobes. Given a cycle of pairs of lobes, the product of the ratios of the volumes of the lobes in each pair is 1. [8]

    en.wikipedia.org/wiki/Voronoi_diagram

    Let H = {h 1, h 2, ..., h k} be the convex hull of P; then the farthest-point Voronoi diagram is a subdivision of the plane into k cells, one for each point in H, with the property that a point q lies in the cell corresponding to a site h i if and only if d(q, h i) > d(q, p j) for each p j ∈ S with h i ≠ p j, where d(p, q) is the Euclidean ...

    en.wikipedia.org/wiki/Mathematics

    Euclidean geometry was developed without change of methods or scope until the 17th century, when René Descartes introduced what is now called Cartesian coordinates. This constituted a major change of paradigm : Instead of defining real numbers as lengths of line segments (see number line ), it allowed the representation of points using their ...
