I came across this problem, I am using Angle2 to check the angle between two lines,the two blue lines are on the same plane, the same direction and the same angle, but for whatever reason the command Angle2 does not return 0.0, as well as the black lines, is something missing?

import rhinoscriptsyntax as rs
line = rs.GetObject(“line”);
line2 = rs.GetObject(“line2”);
point1 = rs.CurveStartPoint(line);
point2 = rs.CurveEndPoint(line);
point3 = rs.CurveStartPoint(line2);
point4 = rs.CurveEndPoint(line2);
angle = rs.Angle2( (point1, point2), (point3, point4))
What is the problem??
