Quadrilateral
Draws a quadrilateral from a set of four points.
quadrilateral(point1, point2, point3, point4)
Example:
quadrilateral(GA, GB, GC, GD) draws quadrilateral
ABCD.
Parallelogram
Draws a parallelogram given three of its vertices. The fourth
point is calculated automatically but is not defined
symbolically. As with most of the other polygon commands,
you can store the fourth point’s coordinates into a CAS
variable. The orientation of the parallelogram is
counterclockwise from the first point.
parallelogram(point1, point2, point3)
Example:
parallelogram(0,6,9+5i) draws a parallelogram
whose vertices are at (0, 0), (6, 0), (9, 5), and (3,5). The
coordinates of the last point are calculated automatically.
Rhombus
Draws a rhombus, given two points and an angle. As with
many of the other polygon commands, you can specify
optional CAS variable names for storing the coordinates of
the other two vertices as points.
rhombus(point1, point2, angle)
Example
rhombus(GA, GB, angle(GC, GD, GE)) draws a
rhombus on segment AB such that the angle at vertex A has
the same measure as ∡ DCE.
Rectangle
Draws a rectangle given two consecutive vertices and a point
on the side opposite the side defined by the first two vertices
or a scale factor for the sides perpendicular to the first side.
As with many of the other polygon commands, you can
specify optional CAS variable names for storing the
coordinates of the other two vertices as points.
