3. Draw a set of concentric pairs of squares, each consisting of a square with horizontal and vertical edges and one rotated through 45 degree. Except for the outermost square, the vertices of each square are the midpoints of the edges of its immediately surrounding square shown in Figure 2. It is required that all lnes are exactly straight, and the vertices of smaller squares lie exactly on the edges of larger ones Computer Graphics (CIS 457) Spring 19 Figure 2: Concentric squares
