Central vs. Inscribed. If you get it straight, you'll be all right!

I could do a column, maybe not a comic, on answering all sorts of question Geometry students might encounter with circles that can be explained using the numbers 90, 180, and 360 along with "half" and "double". (I'm using "half" as an adjective as much as a number there.)

Toss in "similar triangles" and "Pythagorean Theorem" and you can explain most of the rules and theorems you need to solve the Algebra-type problems that get tossed around.

Actually, it might be possible to be sparse with words (to hold the readers' attention) and still have enough background where a proof could be formulated.

Maybe when the break in the semesters comes toward the end of the month.
