WT31: Introduction to Projective Geometry

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.

Remember that you can pause the video to have a good look at the diagrams. It is really a good idea to try to draw some diagrams yourself. That way the notions have a better chance of being retained.

I love this guy! He has a true love for math and is rigorous too.

Thanks for your vids njwildberger.

Just adding my praise. Your videos are a delightful compliment and distraction from my dry text book.

Thanks! It's easier to see geometric reasoning done in a video than just static pictures and text descriptions in a book ..

thank you sir !!!

Nice well done buddy!

Thanks for the video. Two minutes in and I'm starting to grok what projective geometry is about. I could have wasted a lot longer trying to read up on it.

Remarkable lecture with great insight.
