The Pythagorean theorem, a cornerstone of mathematics for millennia, provides a method for determining unknown sides in right-angled triangles using t ...

The hypotenuse of a right triangle is the triangle's longest side; the side opposite the right angle. The length of the hypotenuse of a right triangle can be found using the Pythagorean 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 ...

The Pythagoras Theorem states that in any right-angled triangle, the square of the length of the hypotenuse (c) is equal to the sum of the squares of the lengths of the other two sides (a and b).

The triangle is coloured purple., This triangle will be used to show Pythagoras’ theorem that 𝒂² + 𝒃² = 𝒄². The hypotenuse of the right-angled triangle is labelled as 𝒄.

A classic Pythagorean triple, 3-4-5. To solve for a hypotenuse (the longest side), you must start with a right triangle, which contains a 90-degree angle. From there, you square the length of each ...

The Pythagorean theorem works like this: The hypotenuse of a triangle—the side that is on the opposite side of the 90-degree angle—is equal to the sum of the squares of the other two sides of ...
