The PolyStar tool draws polygons or stars.
from
the pop‑up menu, click and hold the mouse button on the Rectangle
tool and drag.
For Style, select Polygon or Star.
For Number Of Sides, enter a number between 3 and 32.
For Star Point Size, enter a number between 0 and 1 to specify the depth of the star points. A number closer to 0 creates deeper points (like needles). If you are drawing a polygon, leave this setting unchanged. (It does not affect the polygon shape.)
