Two teenage girls in New Orleans just solved a math problem that’s been stumping mathematicians for 2,000 years.  It has to do with the Pythagorean Theorem for sides on a triangle . . . A-squared, plus B-squared, equals C-squared.

That formula is taught in every geometry class, but it’s not ideal because of something called “circular reasoning.”  So they managed to prove it using trigonometry instead, and that’s a big deal.  They just gave a presentation at a math conference this month and were the only high schoolers in the room.
