if one exterior angle of a polygon is 40 degree and others are equal to 20 degrees then how to measure the sides of a polygon
\n" ); document.write( "=========================
\n" ); document.write( "The sum of exterior angles is 360 degs for all polygons.
\n" ); document.write( "40 + n*20 = 360
\n" ); document.write( "n = 16
\n" ); document.write( "--> Sixteen 20 deg angles & one 40 deg angle
\n" ); document.write( "--> 17 sides
\n" ); document.write( "
