Orthocenters exist! | Universal Hyperbolic Geometry 10 | NJ Wildberger

In classical hyperbolic geometry, orthocenters of triangles do not in general exist. Here in universal hyperbolic geometry, they do. This is a crucial building block for triangle geometry in this subject. The dual of an orthocenter is called an ortholine---also not seen in classical hyperb

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.

Projective geometry | Math History | NJ Wildberger

Projective geometry began with the work of Pappus, but was developed primarily by Desargues, with an important contribution by Pascal. Projective geometry is the geometry of the straightedge, and it is the simplest and most fundamental geometry. We describe the important insights of the 19

Introduction to Projective Geometry | WildTrig: Intro to Rational Trigonometry | N J Wildberger

A first look at Projective Geometry, starting with Pappus' theorem, Desargues theorem and a fundamental relation between quadrangles and quadrilaterals. This video is part of the WildTrig series, which introduces Rational Trigonometry and applies it to many different aspects of geometry.

The perspective image of a square II -- more Projective Geometry! | FMP 18b | N J Wildberger

We delve further in Projective Geometry in pursuit of the problem of showing that a general quadrilateral is the perspective image of a square. To prepare the scene, we investigate the role of vanishing points and lines at infinity, first in the two-dimensional case when we project one lin
