The longest side would be the hypotenuse, so
\n" ); document.write( "using the Pythagorean theorem:
\n" ); document.write( " $\"+15%5E2+%2B+17%5E2+=+225+%2B+289+\"$
\n" ); document.write( " $\"+225+%2B+289+=+514+\"$
\n" ); document.write( "Now find the square of the longest side
\n" ); document.write( " $\"+19%5E2+=+361+\"$
\n" ); document.write( " $\"+a%5E2+%2B+b%5E2+=+c%5E2+\"$ is not true, so it can't be a right triangle
