In this chapter, we introduce programming elements for placing and rotating polygons on the screen. The concepts presented are based on the analytical equations derived in Chapter 2.

Although there is no limit to the number of vertices and edges that the polygons can take, for simplicity for this working example, we selected three simple shapes—a square, a triangle, and a skewed-arrow—placed at different positions on the screen. Figure ...
