-Draws a polygon.  The sides of the polygon are defined by the values stored in the array, which should be stored as x,y pairs, sequentially. The length of the array/2 will define the number of points. A polygon may also be specified using an [[anonymousarray|Anonymous Array]] (list of x,y pairs enclosed in curly braces {}).+Draws a polygon.  The sides of the polygon are defined by the values stored in the array, which should be stored as x,y pairs, sequentially. The length of a one dimensional array/2 or the number of rows on a two dimensional array will define the number of points.  
 + 
 +One dimensional arrays and lists must have at least six values and an even number of values.  A two dimensional array may have 3 or more rows but must have two columns.
