Work out the exterior and interior angles of a regular polygon with 18 sides
\n" ); document.write( "--------
\n" ); document.write( "The sum of the Ext angles is 360 degs for all polygons.
\n" ); document.write( "360/18 = 20 degs each
\n" ); document.write( "------
\n" ); document.write( "Int angles = 180 - 20 = 160 degs each.
\n" ); document.write( "18*160 = 2880\r
\n" ); document.write( "\n" ); document.write( "
