By using the Law of Sines, and avoiding the Pythagorean theorem’s trig identity (sin²α + cos²α = 1), Johnson and Jackson successfully proved the theorem without resorting to circular reasoning.

Discovered in the 5 th century B.C. by none other than Pythagoras himself, the Pythagorean Theorem (a 2 + b 2 = c 2) lies at the very foundations of trigonometry.That’s why it was particularly ...

KS3 Maths Pythagoras and trigonometry learning resources for adults, children, parents and teachers.

Ne'Kiya Jackson and Calcea Johnson from Louisiana blew the math community away when they presented a solution to the Pythagorean theorem using trigonometry, an impossible feat for 2,000 years ...

Two high school students have proved the Pythagorean theorem in a way that one early 20th-century mathematician thought was impossible: using trigonometry. Calcea Johnson and Ne’Kiya Jackson ...

While Johnson and Jackson were both familiar with the Pythagorean Theorem’s a² + b² = c² concept, the idea of coming up with a proof using only trigonometry was considered nearly impossible.

Calcea Johnson and Ne'Kiya Jackson surprised the math world when, as seniors in high school, they produced innovative solutions to a 2,000-year-old puzzle.

08/10/2021 August 10, 2021. Most every kid learns a² + b² = c² in math. Pythagoras, right? Wrong. Babylonians used trigonometry 1,000 years before the Greeks.
