New Orleans teens’ Pythagorean proof gains compelling evidence

Calcea Rujean Johnson and Ne'Kiya Jackson's achievement was not the first time trigonometry has been used to prove the theorem

Compelling evidence supports the claims of two New Orleans high school seniors who say they have found a new way to prove Pythagoras's theorem by using trigonometry, a respected mathematics professor said, even if the students' really important and fantastic" achievement is not the first time trigonometry has been used to prove the theory, as their school apparently touted.

Alvaro Lozano-Robledo, of the University of Connecticut, spoke this week in a series of TikTok videos, addressing international reports about Calcea Rujean Johnson and Ne'Kiya Jackson.
