"Nominalism and constructivism in seventeenth-century mathematical philosophy" (PDF).A skew apeirogon is an infinite sequence of sides and angles that do not lie in a flat plane.Equivalently, there exists a line segment between two boundary points that passes outside the polygon.

Monotone with respect to a given line L : every line orthogonal to L intersects the polygon not more than twice.We can't find prices for this accommodation.

Where n is large, this approaches one half.In computer graphics and computational geometry, it is often necessary to determine whether a given point P ( x 0, y 0) lies inside a simple polygon given by a sequence of line segments.
