\n" ); document.write( "If a line intersects two other lines, then it is called a \"traversal\", and there are a total of \"8\" angles formed. Four of the angles are called \"interior\" angles, and four of the angles are called \"exterior\" angles. \r
\n" ); document.write( "\n" ); document.write( " In the \"3\" lines in your graph, line \"t\" is the traversal of lines \"l\" and \"m\", and the \"interior\" angles are \"3\", \"4\", \"5\" and \"6\", while the \"exterior\" angles are \"1\", \"2\", \"7\" and \"8\". \r
\n" ); document.write( "\n" ); document.write( " there are several angle relationships, namely:\r
\n" ); document.write( "\n" ); document.write( " angle \"2\" is equal to angle \"3\"
\n" ); document.write( " angle \"1\" is equal to angle \"4\"
\n" ); document.write( " angle \"5\" is equal to angle \"8\"
\n" ); document.write( " angle \"6\" is equal to angle \"7\"
\n" ); document.write( " angle \"2\" is equal to angle \"6\"
\n" ); document.write( " angle \"4\" is equal to angle \"8\"
\n" ); document.write( " angle \"3\" is equal to angle \"7\"
\n" ); document.write( " angle \"1\" is equal to angle \"5\"\r
\n" ); document.write( "\n" ); document.write( "since angles \"1\" and \"3\" form a \"straight\" line, then they add to \"180\" degrees; so, they are \"supplementary\" angles\r
