The System.Windows.ShapesShape class has a , , and other rendering properties that Geometry and its derived classes lack. The Shape class is a FrameworkElement and therefore participates in the layout system; its derived classes can be used as the content of any element that supports UIElement children.

The Geometry class, on the other hand, simply defines the geometry of a shape, and cannot render itself. Because of its simplicity, it has a wider range of uses.

Freezable Features: Because it inherits from the Freezable class, the Geometry class provides several special features: Geometry objects can be declared as , shared among multiple objects, made read-only to improve performance, cloned, and made thread-safe. For more information about the different features provided by Freezable objects, see Freezable Objects Overview.
