The post Calculate the area of a polygon in C# explains how to calculate the “signed area” of a polygon. That `Polygon` class’s `SignedPolygonArea` method returns a positive area if the polygon is oriented clockwise and a negative area if it is oriented counterclockwise.

The following `PolygonIsOrientedClockwise` method uses `SignedPolygonArea` method to determine whether a polygon is oriented clockwise.

// Return true if the polygon is oriented clockwise. public bool PolygonIsOrientedClockwise() { return (SignedPolygonArea() < 0); }

See the previous post for information about how the `SignedPolygonArea` method works.
