The Pythagorean theorem, which is the square root of the sum of the squares of two sides of a right triangle is equal to the hypotenuse, can be used to find the distance between two points. This means that it can also be used to find the equation of a line.
simply to find area,distance, and perimiter
you can't, because the Pythagorean theorem is for right triangles and the triangles formed by the diagonal of a parallelogram are not right triangles.
You can use pythagorean theorem twice to find the diagonal of a cube
Its simply used to find the distance,area,and perimeter.
You use the pythagorean theorem.
It very much depends on what variable you are trying to find and what information is available.
The Pythagorean theorem is a2 + b2 = c2. It is used for right triangles. If you know two of the sides, you can use the theorem to find the third side.
