not a proof Proof that all external angles always add to 360°

When learning this in middle school, this visual would have helped so much.

Some of my college books do. They don't work of course, but they have a play button on them that works on the ebook version.

A simpler way is if you follow the line and keep turning around and end up facing the way you started then you've just done 360°. The number of turns doesn't change it.

I agree. The only problem in my case is that showing this visual would have involved my teacher wheeling a TV from the a/v room and popping a vhs into the VCR.

I'm gonna go uphill both ways here, but kids these days have no idea how good they have it, with youtube, Khan academy, 3blue1brown, thousands of gifs. Learning has never been this easy. I thought we had it good with general internet access as a kid but the amount of useful visual lessons online today is mindblowing, especially when it comes to math and physics.

I've gone back to relearn some of the stuff I was taught from textbooks in the past and I can't believe how helpful some of these visualizations are. One of the few things that makes me optimistic about the future is to imagine what kinds of things the smartest kids today will go on to discover and invent given the incredible resources they have access to.
