A leading academic has highlighted China’s rich mathematical history, including a startling fact about a well-known theorem.

In this triangle \(a^2 = b^2 + c^2\) and angle \(A\) is a right angle. Pythagoras' theorem only works for right-angled triangles, so you can use it to test whether a triangle has a right angle or not.

When labelling a length as the hypotenuse, it can be shortened to 𝒉. is equal to the sum of the area ... if it is a right-angled triangle check if Pythagoras’ theorem is true for the lengths ...

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.

Ne'Kiya Jackson and Calcea Johnson from Louisiana used trigonometry to prove the 2,000-year-old Pythagorean theorem, which ...

The student's discoveries were confirmed by the math community this week after their proofs were published in the American ...

But it wasn't. The 2,000 year-old theorem states that the sum of the squares on the legs of a right triangle is equivalent to the square on the hypotenuse, or the longest side of a right triangle.
