Which special version of the Pythagorean Theorem can you use to find the length of any square's diagonal, d, using only the leng

kodGreya [7K]

The square's diagonal is the triangle's hypotenuse.

the original Pythagorean theorem is $a^{2} + b^{2} = c^{2}$ where a and b are the two sides and c is the hypotenuse.

that means the Pythagorean theorem for this question is:

$s^{2} + s^{2} = d^{2}$ or $2( s^{2} )= d^{2}$
