Lines and planes in projective geometry | WildTrig: Intro to Rational Trigonometry | N J Wildberger

How to think about both projective points and projective lines via lines and planes in 3D geometry. Also we discuss some basic facts about 3D geometry, relating perpendicularity and quadrances.

This video is part of the WildTrig series, which introduces Rational Trigonometry and applies it to many different aspects of geometry.

My blog is at http://njwildberger.com/, where I will discuss lots of foundational issues, along with other things.

Online courses will be developed at openlearning.com. The first one, already underway is Algebraic Calculus One at https://www.openlearning.com/courses/algebraic-calculus-one/ Please join us for an exciting new approach to one of mathematics' most important subjects!
