Another Gift from Me-of-the-Past

The real reason that I type stuff up to hand out to my class is because then I can use it again in the future.

Found: two proofs to discuss and a follow-up worksheet.

All I need to do is to change the date on the hand-out and make copies, and I'll be all prepped for my class tomorrow.

If I keep things up at this rate, I'll make amazing progress on my extremely ambitious to-do list.
