# How to: Animate the Size of an ArcSegment
This example shows how to animate the <xref:System.Windows.Media.ArcSegment.Size%2A> property of an <xref:System.Windows.Media.ArcSegment>.  
  
## Example  
 The following example creates an <xref:System.Windows.Media.ArcSegment> that animates its <xref:System.Windows.Media.ArcSegment.Size%2A> when it loads on the screen.
