{
if (!circles.ContainsKey(polygon))
{
Triad triad = triangles[polygon];
EllipseGeometry geometry = new EllipseGeometry();
geometry.Center = new Point(triad.CircumcircleX, triad.CircumcircleY);
geometry.RadiusX = geometry.RadiusY = Math.Sqrt(triad.CircumcircleR2);
geometry.Freeze();
Path path = new Path();
Panel.SetZIndex(path, CircleZIndex);
path.StrokeThickness = CircleStrokeTickness;
path.Stroke = new SolidColorBrush(circleStrokeColor);
