A regular polygon's interior angle is 8 times as large as its exterior angle
\n" ); document.write( "

If number of sides are required, then read on!\r
\n" );
document.write( "\n" );
document.write( "Let number of sides be n
\n" );
document.write( "A regular polygon has equal angles and sides
\n" );
document.write( "Therefore, one of its exterior angles is:  (sum of exterior angles of a polygon is ), and one of its interior angles is: 
\n" );
document.write( "We then get: 
\n" );
document.write( "
\n" );
document.write( "180n – 360 = 2,880 ------ Multiplying by LCD, n
\n" );
document.write( "180n = 2,880 + 360
\n" );
document.write( "180n = 3,240
\n" );
document.write( "n, or number of sides = , or  \n" );
document.write( "

\n" );
