The Pythagorean theorem: $\"a%5E2+%2B+b%5E2+=+c%5E2\"$ where a and b are the legs, and c is the hypotenuse.

\n" ); document.write( "To find a leg given the other leg and the hypotenuse: $\"a%5E2+=+c%5E2+-+b%5E2\"$

\n" ); document.write( "In this right triangle call side a = x and c (hypotenuse) = 3x

\n" ); document.write( " $\"%283x%29%5E2+-+x%5E2+=+b%5E2+=+9x%5E2+-+x%5E2+=+8x%5E2\"$

\n" ); document.write( "So $\"b+=+sqrt%288x%5E2%29+=+sqrt%282%2A4%29x+=+2%2Asqrt%282%29x\"$ \n" ); document.write( "

\n" );
