Angle[Vector v1, Vector v2]
Returns the angle between two vectors v1 and v2 (between 0 and 360°) .
Angle[Line g, Line h]
Returns the angle between the direction vectors of two lines g and h (between 0 and 360°) .
Angle[Point A, Point B, Point C]
Returns the angle enclosed by BA and BC (between 0 and 360°), where point B is the apex.
Angle[Point A, Point B, Angle α]
Returns the angle of size α drawn from point A with apex B.

Angle[Conic]
Returns the angle of twist of a conic section’s major axis (see command Axes) .
Angle[Vector]
Returns the angle between the x‐axis and given vector.
Angle[Point]
Returns the angle between the x‐axis and the position vector of the given point.
Angle[Number]
Converts the number into an angle (result between 0 and 2pi).
Angle[Polygon]
Creates all angles of a polygon in mathematically positive orientation (i.e., counter clockwise).
