+# Polygons in GDI+
+A polygon is a closed shape with three or more straight sides. For example, a triangle is a polygon with three sides, a rectangle is a polygon with four sides, and a pentagon is a polygon with five sides. The following illustration shows several polygons.

+  
+## Drawing a Polygon  
+ To draw a polygon, you need a <xref:System.Drawing.Graphics> object, a <xref:System.Drawing.Pen> object, and an array of <xref:System.Drawing.Point> (or <xref:System.Drawing.PointF>) objects. The <xref:System.Drawing.Graphics> object provides the <xref:System.Drawing.Graphics.DrawPolygon%2A> method. The <xref:System.Drawing.Pen> object stores attributes, such as width and color, of the line used to render the polygon, and the array of <xref:System.Drawing.Point> objects stores the points to be connected by straight lines. The <xref:System.Drawing.Pen> object and the array of <xref:System.Drawing.Point> objects are passed as arguments to the <xref:System.Drawing.Graphics.DrawPolygon%2A> method. The following example draws a three-sided polygon. Note that there are only three points in `myPointArray`: (0, 0), (50, 30), and (30, 60). The <xref:System.Drawing.Graphics.DrawPolygon%2A> method automatically closes the polygon by drawing a line from (30, 60) back to the starting point (0, 0).
