Example:
parabola(GA,GB)
draws a parabola whose focus is
point A and whose directrix is line B
parallel With a point and a line as arguments, draws the line through
the point that is parallel to the given line. With a point and a
plane as arguments, draws the plane through the point that is
parallel to the given plane. with a point and two lines as
arguments, draws the plane through the point that is parallel
to the plane made by the two given lines.
parallel(Pnt or Line,Line or Plane,[Line])
Example:
parallel(A, B)
draws the line through point A that is
parallel to line B
parallelepiped Draws a parallelepiped with sides AB, AC, and AD. The faces
of the parallelepiped are parallelograms.
parallelepiped(Pnt(A),Pnt(B),Pnt(C),Pnt(D))
parallelogram Draws the parallelogram ABCD such that
vector(AB)+vector(AD)=vector(AC).
parallelogram(Pnt(A)||Cplx,Pnt(B)||Cplx,Pnt(C
)||Cplx,[Var(D)])
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.
perimeterat Displays the perimeter at point z0 of a circle or polygon. A
legend is provided.
perimeterat(Polygon,Pnt||Cplx(z0))
perimeteratraw Displays the perimeter at point z0 of a circle or polygon.
perimeteratraw(Polygon,Pnt||Cplx(z0))
