Join a Line and Ellipse - join

Question

I did find how to bind a line to an ellipse through XAML, but I'm not very familiar with binding, and though I've researched it, I still don't understand how to get binding to work with user input.
Is there a way, programmatically to have an ellipse joined to the end of a line so when the line rotates on a diameter, the ellipse rotates with it? Everything I wrote for this is done in the code, not XAML.

Answer 1

Never mind, I figured it out. I posted the segment of code that provided the answer.
Rads = Math.PI * ang / 180;
x1 = Math.Sin(Rads) * 80;
y1 = Math.Cos(Rads) * 80;
x2 = Math.Sin(Rads) * 30;
y2 = Math.Cos(Rads) * 30;
Ellipse ellA = new Ellipse();
ellA.Width = 10;
ellA.Height = 10;
ellA.Stroke = Brushes.Black;
ellA.Fill = Brushes.Lime;
TranslateTransform ella1 = new TranslateTransform(70 + x1, 145 - y1);
ellA.RenderTransform = ella1;
freeCanvas.Children.Add(ellA);
Ellipse ellB = new Ellipse();
ellB.Width = 10;
ellB.Height = 10;
ellB.Stroke = Brushes.Black;
ellB.Fill = Brushes.Yellow;
TranslateTransform ellb1 = new TranslateTransform(70 + x2, 145 - y2);
ellB.RenderTransform = ellb1;
freeCanvas.Children.Add(ellB);
