I am putting together a quick and it-should-be easy assignment on the Pythagorean Theorem right now, to make up for an assignment on the Pythagorean Theorem from late last week that did not turn out to be easy. It contains this question:

There is an absolutely 100% certainty that someone will come up to me and say something along the lines of “Why are there four numbers here?” And then I will say “Can you make a triangle with four sides?” And they will say “No.” And then I will say “Well, then, can those sides make a right triangle?” And they will not know the answer, and they will stare at me, with big, cow-like eyes.

I am tired and perhaps a bit crabby.
