Mode regularpolygon 32.gif - Regular polygon

Action: This tool allows you to create a regular polygon of any number of sides.


Usage: Click where you wish to place the first two vertices (A and B). A dialog box will then open to allow you to specify the number of sides (n).


Notes:

  • The polygon will be traced out in a counter-clockwise direction, starting with the side from A to B.
  • Several objects will be created by this tool:
    • The new vertex points will appear in the algebra window as free objects.
    • The edge line segments and vertices will appear in the algebra window as dependent objects.
    • The area of the polygon will appear in the algebra window as a dependent object.
  • The polygon may be abandoned by pressing the Cancel button in the dialog box, but any points will remain.
  • Nonsense values in the dialog box will result in two line segments between the initial points.


Tips:

  • Holding down the mouse button while creating a point will display its coordinates, allowing you to position it precisely.
  • You may use existing points for one or both of the initial vertices, A and B.


Equivalent Command: Polygon[point A, point B, number n]
