Pythagoras' theorem describes the relationship between the three sides of a right-angled triangle. It is incredibly useful for engineering and construction and was used by humans centuries before ...

A high school teacher didn't expect a solution when she set a 2,000-year-old Pythagorean Theorem problem in front of her students. Then Calcea Johnson and Ne'Kiya Jackson stepped up to the challenge.

McNulty shows a new proof of the Pythagorean theorem using trigonometry in a diagram like the image below.

“There was a bonus question that was to create a new proof of the Pythagorean Theorem,” Johnson says of the mathematic cornerstone that helps find the missing side length of a right triangle.

A Theorem Tested Through Time For over 2,000 years, Pythagoras’ theorem has stood as one of the cornerstones of mathematics. It states that in a right-angled triangle, the sum of the squares of ...

Ne’Kiya Jackson and Calcea Johnson have published 10 trigonometric proofs of the Pythagorean theorem, a feat thought impossible for 2,000 years.

Hundreds of years before a Greek scholar outlined his proof of the Pythagorean theorem, ancient Chinese scholars proved it using just 17 characters, a renowned Chinese mathematician highlighted in ...

In this article we present some elementary proofs of the 60-degree and 120-degree counterparts of Pythagoras′ theorem that mimic the two (most) famous one-glance proofs of Pythagoras′ theorem.

The theorem’s history, however, is more complex than this legend would suggest. The use of the 3-4-5 triangle for constructing a right angle, for instance, goes back to much earlier times in ...
