I have a dynamic list of strings with length "n" and need to draw a circle divided into "n" number of equal parts and distribute the name in parts.
I found this Xaml piece of code that generates 3 parts but I can't figure how to do it programmatically

Is it even a good way? if not, what is the best way to generate what I need?
What really confuses me is how to calculate the ArcSegment value?
DrawingGroup drawingGroup = new DrawingGroup();
var lastPoint = new Point(100, 0);
for (int i = 0; i < 3; i++)
{
GeometryDrawing drawing = new GeometryDrawing();
drawing.Brush = (Brush)new BrushConverter().ConvertFrom("#FF0000"); // TODO: change color
drawing.Pen = new Pen
{
Brush = (Brush)new BrushConverter().ConvertFrom("#000000")
};
PathSegment lineSegment1 = new LineSegment(lastPoint, true);
lastPoint = new Point(200, 100); // TODO: calculate
PathSegment arcSegment = new ArcSegment(lastPoint, new Size(100, 100), 0, false, SweepDirection.Clockwise, true);
PathSegment lineSegment2 = new LineSegment(new Point(100, 100), true);
PathFigure figure = new PathFigure(new Point(100, 100), new PathSegment[] { lineSegment1, arcSegment, lineSegment2 }, false);
drawing.Geometry = new PathGeometry(new PathFigure[] { figure });
drawingGroup.Children.Add(drawing);
}
Thanks in advance.
