PathGeometry is a class in the System.Windows.Media namespace. It represents a complex shape that may be composed of lines, arcs, points, polygons, etc. PathGeometry has several useful methods that can help in detecting overlap of shapes and overlapping areas. Also, it has methods for handling various operations necessary when working with odd shapes.
