Thanks +Susan Jones
for the feedback.
I have watched a few examples where the c^2 was split into pieces that were difficult to determine the "why" as you mention here. I tried to make it more obvious that I needed to "wrap around" the area of the b by b square. However, I definitely see your point now that I think about it more deeply.
I would have to do some thinking to find a way to show it while maintaining the simplicity that I am aiming for with these videos.
If you have some thoughts on this, please do share! Thanks for watching!
