How is the length of a diagonal of a square found?

As a square has right angles, the diagonal forms a right triangle with two of the sides of the square. Therefore use Pythagoras: diagonal² = side² + side² → diagonal² = 2side² → diagonal = side × √2 Therefore to find the length of the diagonal of a square, multiply the side length of a square by the square root of 2.

How do you find the diameter of a square?

Squares do not have diameters; circles have them. If you are referring to the diagonal of a square, then you would use Pythagorean's Theorem to determine the length of the diagonal. 'Square' the length of one side and multiply by 2, then take the square root of that number to get the length of the diagonal. that is = under root( 2 s) where s= side
