\n" ); document.write( "\n" ); document.write( "to know if the \"15\",\"36\",\"39\" is right triangle, use Pythagorean theorem:\r
\n" ); document.write( "\n" ); document.write( "\"c%5E2=a%5E2%2Bb%5E2\"....\"a=15\",\"b=36\",\"c=39\"\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "\"39%5E2=15%5E2%2B36%5E2\"\r
\n" ); document.write( "\n" ); document.write( "\"1521=225%2B1296\"\r
\n" ); document.write( "\n" ); document.write( "\"1521=1521\" => true; so, these are the sides of the right triangle
