Polygons
A polygon is a closed figure defined by a set of points. The main advantage of using a polygon object versus building one from line objects is that a polygon can be shaded in. Additionally the attributes of the outline of the polygon can be changed as a whole instead of having to do it individually for each side. Points and arrows, however, can not be attached to the outline of a polygon. Many pre-made polygons are available using a shape object.
Create a Polygon
Select at least 3 points. To do this hold down the key, click on each point, and then release the key. The order of the point selection determines how the sides of the polygon are drawn. A side will automatically be drawn between the first selected and the last points selected.
