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.

备注： The point Rotate[A, α, B] is created as well.

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).

备注： If the polygon was created in counter clockwise orientation, you get the interior angles. If the polygon was created in clockwise orientation, you get the exterior angles.
