Example:
plotlist([[0,3],[2,1],[4,4],[0,3]]) draws a
triangle
Slider
Creates a slider bar that can be used to control the value of
a parameter. A dialog box displays the slider bar definition
and any animation for the slider. When completed, the slider
bar appears near the top left of Plot view. You can then move
it to another location.
Transform
Translation
Translates a geometric object along a given vector. The vector
is given as the difference of two points (head-tail).
translation(vector, object)
Examples:
translation(0-i, GA) translates object A down one
unit.
translation(GB-GA, GC) translates object C along the
vector AB.
Reflection
Reflects a geometric object over a line or through a point. The
latter is sometimes referred to as a half-turn.
reflection(line, object) or reflection(point,
object)
Examples:
reflection(line(x=3),point(1,1)) reflects the
point at (1, 1) over the vertical line x=3 to create a point at
(5,1).
reflection(1+i, 3-2i) reflects the point at (3,–2)
through the point at (1, 1) to create a point at (–1, 4).
Rotation
Rotates a geometric object, about a given center point,
through a given angle.
rotate(point, angle, object)
