Incidence geometry | Families of sets
In geometry, a generalized quadrangle is an incidence structure whose main feature is the lack of any triangles (yet containing many quadrangles). A generalized quadrangle is by definition a polar space of rank two. They are the generalized n-gons with n = 4 and near 2n-gons with n = 2. They are also precisely the partial geometries pg(s,t,α) with α = 1. (Wikipedia).

The Three / Four bridge in Triangle Geometry: Incentres and Orthocentres | Six 6 | Wild Egg
We look at how to cross the Three / Four bridge geometrically: in both directions. This connects with some classical triangle geometry, involving triangle centres going back to ancient Greek geometry. We will touch base with the algebraic orientation to angle bisection, modifying a little

Cycles and the Three/Four bridge | Six: An elementary course in Pure Mathematics Six 3 | Wild Egg
Continuing our study of six things, we introduce Cycles, along with Quadrangles and Pentagons. Then we have a closer look at the Three/Four bridge, a fundamental connection between four things and three things which we have already met in the context of Meets associated to an Edge and the

Conics are fundamental curves in mathematics that have been studied since ancient times. Here we introduce very simple kinds of conics that are closely related to Cycles and Meets for four Nodes. This gives us a chance to review some basics of analytic geometry, and how we represent both

Apollonius and polarity revisited | Universal Hyperbolic Geometry 13 | NJ Wildberger
Armed with explicit formulas for null points and null lines, along with their meets and joins, we return to the polarity of Apollonius with which we began this series. Our aim is to establish a fundamental fact that was previously stated without proof: that the dual or polar of a point can
