The tablet known as Plimpton 322, dated to around 1800 BCE, contains 15 rows of numbers linked to Pythagorean triples ...

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 ...

August 15, 2017 (8/15/17) was Pythagorean Theorem Day (see I missed Pythagorean Theorem Day). I was not even aware that there was such a day until this year, but it brought to my attention some really ...

In this math tutorial, we explore how to find the missing side of a right triangle using the pythagorean theorem. We'll ...

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, ...

a 2 + b 2 = c 2. Remember that from high school math class? That's the Pythagorean theorem, which shows that in a right triangle, where the shorter legs are a and b, the sum of their squares is equal ...

The standard Pythagorean theorem is used on an everyday basis in professions like architecture, building construction, navigation, spaceflight, computer sciences, and more. Calcea Johnson and Ne’Kiya ...

Catherine Scarlett responds to an article about US teenagers who claim to have proved the theorem using trigonometry While it is heartening to see enthusiastic mathematical inquiry in young people and ...

You might think that once a theorem has been proved that would be the end of it. I mean, is there possibly any value in having another proof of something? A new proof certainly doesn't make a theorem ...
