as the number of sides, n approaches infinity, the internal angle approaches 180 degrees. for a regular polygon with 10,000 sides (a myriagon) the internal angle is 179.964°. as the number of sides increase, the internal angle can come very close to 180°, and the shape of the polygon approaches that of a circle. however the polygon can never become a circle. the value of the internal angle can never become exactly equal to 180°, as the circumference would effectively become a straight line. for this reason, a circle is not a polygon with an infinite number of sides.
