US teens say they have new proof for 2,000-year-old mathematical theorem

New Orleans students Calcea Johnson and Ne'Kiya Jackson recently presented their findings on the Pythagorean theorem

Two New Orleans high school seniors who say they have proven Pythagoras's theorem by using trigonometry - which academics for two millennia have thought to be impossible - are being encouraged by a prominent US mathematical research organization to submit their work to a peer-reviewed journal.

Calcea Johnson and Ne'Kiya Jackson, who are students of St Mary's Academy, recently gave a presentation of their findings at the American Mathematical Society south-eastern chapter's semi-annual meeting in Georgia.
