The sum of the interior angles is \"180%28n-2%29\" since you can draw n-2 non-overlapping triangles within the polygon.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "The sum of all the interior and exterior angles is simply \"180n\". If we subtract the total sum of the interior angles, we get \"180n+-+180%28n-2%29\", or 360 degrees.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Not enough information for the third one, but the average measure is also the measure of an angle of a regular n-gon, or \"180%28n-2%29%2Fn\".
