Find the number of sides of a polygon if the sum of the measures of its interior angles is twice the sum of measures of its exterior angle.
\n" ); document.write( "-----------------
\n" ); document.write( "The sum of exterior angles = 360 for all polygons.
\n" ); document.write( "--> 720 for internal angles
\n" ); document.write( "-----------
\n" ); document.write( "720 = 180*(n-2)
\n" ); document.write( "n = 6 sides
\n" ); document.write( "
