{Binding} is a markup extension, a special syntax in XAML. And StartPoint="{Binding StartPoint.X, ElementName=UpperCircle},150" is not XAML-compliant.

Try this:

<PathFigure  x:Name="LeftLine"
        StartPoint="{Binding ElementName=UpperCircle,Path=StartPoint}" 
        >
    <LineSegment Point="50,280" />
</PathFigure>

If you want to know about XAML syntax and Binding, the following documents can help you:

  1. XAML overview
  2. Data binding overview

Best regards.
