Use a protractor, geometry, and Snell's Law, and keep answer to two decimals places. If you don't have a protractor, google "printable protractors" and print your favorite."
So what do you think? This one is kind of cute, though the one from here comes with a handy formula sheet. For those of us who don't care about the fancy stuff, I suppose that the Print A Protractor page works just as well.
Sorry, I couldn't resist. Summer classes apparently make me dorkier than usual. Who knew?
Cats have tried to eat my eraser yesterday, and Simba seemed to have grown quite fond of Kate's shoes, so I must move them into her room before he decides to do anything interesting with them (trust me, with cats, "interesting" is EXACTLY the right word). Found a dessicated brussel sprout in the back of the freezer yesterday.

Protractors are one of those objects I have an odd infatuation with. Though my love for protractors isn't as big as for some other things. Still, I used to really like using it. In Moscow everyone had in math, like everyone'd have a pencil.
