@robinhouston neat! I'm going to challenge one of my kids to try proving these, if she dare, at least the first one. assuming I can prove them to myself this evening.

@aadmaa2 @robinhouston I was able to prove all of them right now, but some with more difficulty than others. The first and last equation on the top row fell out immediately from the figure I drew, while the remaining three equations required a bit of algebraic manipulation (and a bit of trial and error to find those algebraic manipulations).
