13.6.4 Defining random points in the plane: point2d
The point2d command defines a random point whose coordinates
are integers between -5 and 5.
-
point2d takes an unspecified number of arguments:
names, a sequence of names for the points.
- point2d(names) assigns a random
point whose coordinates are integers between -5 and 5 to each name.
Examples.
-
Input:
point2d(A))
This assigns A to a random point. Once assigned, the point
is fixed.
- Input:
point2d(A,B,C) |
triangle(A,B,C)
|
generates three random points and uses them to create a triangle;
i.e., it creates a random triangle.
