You can use pythagorean theorem twice to find the diagonal of a cube
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.
The Pythagorean Theorem is used to find side lengths of right triangles. It came from the Greek philosopher and mathematician Pythagoras.
You would use the Pythagorean Theorem when you are trying to determine the length of a side on a right triangle.ORYou might use the Pythagorean Theorem if you are carpenter or builder. A carpenter might use the Pythagorean Theorem to find the length of the hypotenuse (longest side of the triangle) or the length of the wall or roof. Use can use this methed or theorem in any building situation.
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.
Sure there is. You can find some here. http://www.math-aids.com/Pythagorean_Theorem/ Also, the website below will work as well. http://www.mathworksheetscenter.com/mathskills/geometry/PythagoreanTheorem3geo/
It depends on what x is and what information you have. For example, if no side lengths are known, the Pythagorean theorem is not going to be any use!
it can help you find the unknown length on one side of a triangle
it helps to find the side measures of a right triangle
If you have two lengths of the triangle, the Pythagorean theorem will help you find the third. As it is, you need to find two numbers whose squares add up to 1296. There are a lot of possibilities.
