Constructible polygons are polygons that can be drawn using only a straightedge and compass, following the rules of classical geometric construction as described by ancient Greek mathematicians. A polygon is constructible if it can be formed by a finite number of steps using these tools, starting from a given set of points. A critical condition for a polygon to be constructible is related to its angles.
