Reflect this triangle over the line \"y=-x\"\r
\n" ); document.write( "\n" ); document.write( "Point \"A\"(\"2\",\"1\")
\n" ); document.write( "Point \"B\"(\"2\",\"3\")
\n" ); document.write( "Point \"C\"(\"3\",\"1\")\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "\r
\n" ); document.write( "\n" ); document.write( " If you reflect over the line \"y+=+-x\", the \"x\"-coordinate and\"+y\"-coordinate change places and are negated (the signs are changed).\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Point \"A%5B1%5D\"(\"-1\",\"-2\")
\n" ); document.write( "Point \"B%5B1%5D\"(\"-3\",\"-2\")
\n" ); document.write( "Point \"C%5B1%5D\"(\"-1\",\"-3\")\r
