The Polygon Tool can be used to create regular polygons or stars within a drawing. To create a polygon, simply select the tool and then use a Touch/Drag gesture combination at the point in the drawing canvas where the center of the polygon will be. Then drag in any direction and release the Touch action where one of the outer points of the polygon should reside on the drawing canvas.
The number of polygon sides can be specified prior to drawing the shape or altered any time after it has been created. To set the number of sides:
Select the polygon to be altered.
Press on the Shape Specific option.
Use the # of Sides option to set the number of sides for a polygon. Tap on the "up" or "down" buttons to change the value or press on the text entry field to bring up a keypad for entering the value by hand.
In the example below, the value has been changed to 8.
Note: A polygon can also contain text. See Handling Text for further details.
