Angle
Reading time: 1minComputes the angle between two objects. If geometry_status=2, then angle=angle2d; if geometry_status=3, then angle=angle3d.
Syntax
angle2d(Conic)
angle2d(Line)
angle2d(Line, Line)
angle3d(Plane, Line)
angle3d(Plane, Plane)
angle3d(Plane, Segment)
angle(Point, Point, Point)
angle(Polygon, Integer)
angle(Triangle, Integer)
Description
Computes the angle between a conic and the line {y=0}. 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.
Computes the angle between a line and the horizontal axis.
Computes the angle between two lines.
Computes the angle between a plane and a line.

Given three points A, B and C, computes the angle between the lines created joining the points A and B, and B and C.
Given a polygonal or polygon and an integer i, computes the angle of the i-th vertex.
Given a triangle and an integer i, computes the angle of the i-th vertex.
