I have this code for style

    <Style  x:Key="Mystyle" TargetType="Button">
        <Setter Property="Template">
            <Setter.Value>
                <ControlTemplate TargetType="{x:Type Button}">
                    <Grid >
                        <Polygon Name="poly"  Points="0,0 0,100 50,200"
                         Fill=" TemplateBinding Background}"                            
                        <ContentPresenter HorizontalAlignment="Center"
                                      VerticalAlignment="Center"/>
                    </Grid>
                </ControlTemplate>

Why dont you just create new dependency property(of a type PointCollection?) and bind Polygon's Points property against it? Then do your calculations when needed(@code-behind), and UI will automatically understand.

Here is an example(using ObservableCollection); http://social.msdn.microsoft.com/Forums/en-US/wpf/thread/1293d4cb-87b3-4cdc-97e3-ae2f41caf2d4/
