Finite geometry | Projective geometry
In mathematics, a non-Desarguesian plane is a projective plane that does not satisfy Desargues' theorem (named after Girard Desargues), or in other words a plane that is not a Desarguesian plane. The theorem of Desargues is true in all projective spaces of dimension not 2; in other words, the only projective spaces of dimension not equal to 2 are the classical projective geometries over a field (or division ring). However, David Hilbert found that some projective planes do not satisfy it. The current state of knowledge of these examples is not complete. (Wikipedia).
Here we show a quick way to set up a face in desmos using domain and range restrictions along with sliders. @shaunteaches

algebraic geometry 16 Desargues's theorem
This lecture is part of an online algebraic geometry course, based on chapter I of "Algebraic geometry" by Hartshorne. It covers Desargues's theorem and duality of projective space.

Points, Lines, Planes, Segments, & Rays - Collinear vs Coplanar Points - Geometry
This geometry video tutorial provides a basic introduction into points, lines, segments, rays, and planes. It explains how to identify three collinear points and how to distinguish it from noncollinear points. It explains the difference between coplanar points and noncoplanar points. Th

What are Planar Graphs? | Graph Theory
What are planar graphs? How can we draw them in the plane? In today's graph theory lesson we'll be defining planar graphs, plane graphs, regions of plane graphs, boundaries of regions of plane graphs, and introducing Euler's formula for connected plane graphs. A planar graph is a graph t

Control systems with non-minimum phase dynamics
This video describes control systems that have non-minimum phase dynamics, characterized by a zero of the input--output transfer function in the right-half-plane. Physically, these systems "go in the wrong direction" initially when control is applied, before turning around and going in th
