Does \"a%5E2+%2B+b%5E2+=+c%5E2\" where c is the longest side?
\n" ); document.write( "\"5%5E2+%2B+8%5E2+=+c%5E2\"
\n" ); document.write( "\"25+%2B+64+=+89%7D%7D%0D%0A%7B%7B%7Bc+=+9\"
\n" ); document.write( "\"c%5E2+=+81\"
\n" ); document.write( "a2 + b2 does not equal c2, not a right triangle
\n" ); document.write( "------------------
\n" ); document.write( "\"18%5E2+%2B+24%5E2+=+324+%2B+576\"
\n" ); document.write( "\"324+%2B+576+=+900\"
\n" ); document.write( "\"c%5E2+=+30%5E2\"
\n" ); document.write( "\"c%5E2+=+900\"
\n" ); document.write( "a2 + b2 = c2, so it's a right triangle
\n" ); document.write( "
