The sum of the interior angles of a polygon is given by:
\n" ); document.write( " $\"S+=+180%28n-2%29\"$ degrees, where n = the number of sides in the polygon.
\n" ); document.write( "For example, the sum of the interior angles of an octgagon (n=8) would be:
\n" ); document.write( " $\"S+=+180%288-2%29\"$
\n" ); document.write( " $\"S+=+180%286%29\"$
\n" ); document.write( " $\"S+=+1080\"$ degrees. \n" ); document.write( "
