The diagonal creates a right triangle with two sides being the sides of the square. Let x be the length of the side:\r
\n" ); document.write( "\n" ); document.write( "Then by the Pythagorean Theorem we have:\r
\n" ); document.write( "\n" ); document.write( "x^2 + x^2 = 12^2
\n" ); document.write( "2x^2 = 144
\n" ); document.write( "x^2 = 72
\n" ); document.write( "x = sqrt(72)
\n" ); document.write( "x = sqrt(36*2)
\n" ); document.write( "x = sqrt(36)*sqrt(2)
\n" ); document.write( "x = 6*sqrt(2)\r
\n" ); document.write( "\n" ); document.write( " \n" ); document.write( "
