Thank you for your help!

    Dont know C# but in lisp its just a simple case of (angle pt1 pt2) the angle is returned as per your image basleine is zero to right. The only thing would be if want a selected segment then need extra code to work out which segment from the vertice points. So start with C# get pline vertices.

    maybe something like
    LineSegment2d Polyline.GetLineSegment2dAt(int index);
    LineSegment2d.Direction.Angle, convert to degrees if its radians.
