Use Pythagoras’ theorem to show a triangle is right-angled or to find one side of a right-angled triangle when two sides are known. Make sure you are confident at substituting into and manipulating ...

The longest side of a right-angled triangle is the hypotenuse. The hypotenuse is always opposite the right angle. Draw a square on each side of a right-angled triangle. Calculate the area of each ...

The Pythagorean Theorem—discovered by the Greek mathematician Pythagoras in the 6th century BCE—is a cornerstone of mathematics. Simply stated as a 2 + b 2 = c 2, the theorem posits that the sum of ...

In 2022, U.S. high school students Calcea Johnson and Ne'Kiya Jackson astonished teachers when they discovered a new way to prove Pythagoras' theorem using trigonometry after entering a competition at ...

The Pythagorean Theorem is an ancient theory that states that in a right triangle, if the length of the hypotenuse is c, and the lengths of the two sides that sandwich the right angle are a and b, ...

There are few prehistoric monuments still standing that have catalyzed as much intrigue as Stonehenge. The Neolithic and Bronze Age structure may have been built as early as 3000 BC, and yet ...

Stonehenge was built using Pythagoras’ theorem – two millennia before the Greek philosopher was born, say experts. The builders of Britain’s ancient stone circles are said to have used complex ...
