Como: Arredondar os Cantos de um RectangleGeometry
To round the corners of a RectangleGeometry, set its RadiusX and RadiusY properties to a value greater than zero. The larger the values, the rounder the rectangle's corners.
Exemplo
The following example shows several RectangleGeometry objects with different RadiusX and RadiusY settings. The RectangleGeometry objects are displayed using Path elements.
