Pythagoras’ theorem can also be used to find missing lengths in shapes, such as rectangles and isosceles triangles close isosceles triangle A triangle with two equal sides. This means two angles ...

When it comes to the Pythagorean Theorem, however, you might think we'd be satisfied.Indeed, the Wikipedia page lists at least a half-dozen proofs, so it's not clear that we need another. But ...

Study Limitations. The first four proofs presented in the paper have a notable limitation: they don’t work for isosceles ...

The fifth proof even captures both isosceles and non-isosceles triangles in one go. As if that was not enough, the pair also claim to have found five additional proofs using the same basic method ...

Their accomplishment adds to the rich history of proofs of the Pythagorean theorem, which states that in a right-angled ...

In fact, there have been hundreds of proofs of the Pythagoras’ groundbreaking theorem, but almost none of them—if not none at all—have independently proved it using trigonometry.

Two high school seniors have presented their proof of the Pythagorean theorem using trigonometry — which mathematicians thought to be impossible — at an American Mathematical Society meeting.

At an American Mathematical Society meeting, high school students presented a proof of the Pythagorean theorem that used trigonometry—an approach that some once considered impossible ...

In a new peer-reviewed study, Ne'Kiya Jackson and Calcea Johnson outlined 10 ways to solve the Pythagorean theorem using trigonometry, including a proof they discovered in high school.

A University of Tartu student has come up with a new proof of the Pythagorean theorem using origami. While folding paper is already used — even in basic school — to demonstrate the well-known ...

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.
