A quadrilateral assignment is a list of 4 variable names followed by the
word parallelogram
, rectangle
or square
and some optional parameters. If the first variable is already defined as a
point, the quadrilateral is constructed from this point. If not, the point is
set to origin. The optional parameter b is the polar angle of segment AB
(default: 0°). Here are all the ways to define a quadrilateral:
A B C D parallelogram[(x, y, a [,
b])]
A B C D parallelogram(u, v [, b])
A B C D rectangle[(x, y [, b])]
A B C D square[(x [, b])]
A pentagon assignment is the following command:
A B C D E pentagon(F, x, a)
An hexagon assignment is the following command:
A B C D E F hexagon(G, x, a)
