@griftorifto2 Yes, I asked my math teacher the following day and got it explained. Thank you for the response anyways.

@turquoiseguy Pythagoras theorem(s) to get step before that. Then multiplied it out and moved formula around

I love how I could pretty much prove this on my own before I even watched this video. Yet a few moths ago a I barely passed my test by 1%
. Somehow khan academy has boosted me beyond ever actually needing to watch the videos. Like I find everything so easy in class now having it explained to me twice is useless. Thanks Khan, I love math!

Dang.. that's pretty awesome! :)
