[izvsgyut] A whole circle in a piece

Circles are neat because seeing any portion of the arc is enough to uniquely determine the radius and center.  This is not true for other shapes. For regular polygons with small numbers of sides, we need to see the regions around at least 2 vertices, which are only a small parts of the whole perimeter.  Most of the perimeter of a polygon is a line, completely useless for telling anything about the polygon.
