In a right triangle, \"a%5E2\"+\"b%5E2\"=\"c%5E2\" where a and b are the legs and c is the hypotenuse.
\n" ); document.write( ".
\n" ); document.write( "3^2 + 6^2 = x^2
\n" ); document.write( "9 + 36 = x^2
\n" ); document.write( "45 = x^2
\n" ); document.write( "Take the square root of each side to get
\n" ); document.write( "6.7082 = x (or \"the square root of 45\")
\n" ); document.write( ".
\n" ); document.write( "For the second equation, a rectangle is simply two right triangles together. Same formula.
\n" ); document.write( "10^2 + 8^2 = x^2
\n" ); document.write( "100 + 64 = x^2
\n" ); document.write( "164 = x^2
\n" ); document.write( "12.0862 = x (or \"the square root of 164\")
\n" ); document.write( "
\n" );
