Quadrilaterals, quadrangles and n-gons | Arithmetic + Geometry Math Foundations 45 | N J Wildberger

Precise definitions are important! Especially in geometry, where traditional texts too often just assume that the meanings of the main terms are obvious. Quadrilaterals, quadrangles and n-gons are good examples. This video belongs to Wildberger's MathFoundations series, which sets out a c

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

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

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

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

The Three / Four bridge plays an important role in understanding the remarkable duality discover by Apollonius between points and lines in the plane once a conic is specified. This is a purely projective construction that works for ellipses, and their special case of a circle, for parabola
