Angle

Computes the angle between two objects. If geometry_status=2, then angle=angle2d; if geometry_status=3, then angle=angle3d.

angle2d(Conic)

Computes the angle between a conic and the line left curly bracket y equals 0 right curly bracket. For instance, if the conic is an ellipse, the angle computed is the angle formed by the line passing through the focus and the horizontal axis. If the conic is a parabola, the axis of symmetry is considered.

angle2d(Line)

Computes the angle between a line and the horizontal axis.

angle2d(Line, Line)

Computes the angle between two lines.

angle3d(Plane, Line)

Computes the angle between a plane and a line.

angle3d(Plane, Plane)

Computes the angle between two planes.

angle3d(Plane, Segment)

Computes the angle between a plane and the line defined by a segment.

angle(Point, Point, Point)

Given three points A, B and C, computes the angle between the lines created joining the points A and B, and B and C.

angle(Polygonal | Polygon, Integer)

Given a polygonal or polygon and an integer i, computes the angle of the i-th vertex.

angle(Triangle, Integer)

Given a triangle and an integer i, computes the angle of the i-th vertex.
