We have learned how to draw rectangle, ellipse, circle and text in the preceding chapters, now let’s learn how to draw polygons on the screen. Besides that, we shall also learn how to draw pie.<\/p>\n

25.1: Drawing Polygons<\/h3>\n

Polygon is a closed plane figure bounded by three or more straight sides. In order to draw a polygon on the screen, we need to define the coordinates of all the points (also known as vertices) that joined up to form the polygon.<\/p>\n

The syntax to defines the points of a polygon with vertices A1, A2, A3, \u00a0A4…….An is as follows;<\/p>\n

Dim A1 As New Point(X1,Y1)\r\nDim A2 As New Point(X2,Y2)\r\nDim A3 As New Point(X3,Y3)\r\nDim A4 As New Point(X4,Y4)\r\n.\r\n.\r\nDim An as New Point(Xn,Yn)\r\n<\/pre>\n
