\n" ); document.write( "\n" ); document.write( "to determine if it is a right triangle, use Pythagorean theorem\r
\n" ); document.write( "\n" ); document.write( "\"80%5E2=20%5E2%2B40%5E2\" \r
\n" ); document.write( "\n" ); document.write( "\"6400=400%2B1600\"\r
\n" ); document.write( "\n" ); document.write( "\"6400=2000\"-> false\r
\n" ); document.write( "\n" ); document.write( "since \"6400%3C%3E2000\", it is \"not\" a right triangle
