I have a question on the way to find the sides of an isosceles right triangle with a hypotenuse that is radical 72.

\n" ); document.write( "You need to find one of the sides of the square before you can determine the perimeter of the square.
\n" ); document.write( "Since it’s a square, each side can be named, S
\n" ); document.write( "Since \"a%5E2+%2B+b%5E2+=+c%5E2\", then we’d have: \"S%5E2+%2B+S%5E2+=+%28sqrt%2872%29%29%5E2\", and you could solve for S. Then you’d be able to find the perimeter.\r
\n" ); document.write( "\n" ); document.write( "However, what the professor is saying is that when a 45-45-90 special triangle exists
\n" ); document.write( "(and this does occur in a square), and one of the sides is named S, the hypotenuse (the diagonal in this case)
\n" ); document.write( "is \"S+%2A+sqrt%282%29\". Now, since it’s given that the diagonal or hypotenuse is \"sqrt%2872%29\", it then follows that:
\n" ); document.write( "\"S+%2A+sqrt%282%29+=+sqrt%2872%29\"
\n" ); document.write( "\"%28S+%2A+sqrt%282%29%29%5E2+=+%28sqrt%2872%29%29%5E2\" -------- Squaring both sides
\n" ); document.write( "\"S%5E2+%2A+2+=+72\"
\n" ); document.write( "\"2S%5E2+=+72\"
\n" ); document.write( "\"S%5E2+=+72%2F2\"
\n" ); document.write( "\"S%5E2+=+36\"
\n" ); document.write( "S = \"sqrt%2836%29\", or 6\r
\n" ); document.write( "\n" ); document.write( "With S or one side being 6, the perimeter is: 4(6), or \"highlight_green%2824%29\" cm \n" ); document.write( "
\n" );
