Use
            the Rectangle object tool to draw a rectangle or square in one of
            two ways:
         
         
            - Corner-to-corner, with the two vertices
               located at diagonally opposite corners of the rectangle
            
- Centre-to-corner, with the first vertex
               at the centre of the rectangle and the second at one corner
            
To draw a rectangle from corner-to-corner:
         
         
            - In the Graphics menu, click Add.
            
- Select the Rectangle tool in the Object
               Tools window.
            
- Press the cursor to anchor one corner
               of the rectangle. Do not release the cursor.
            
- Drag the cursor diagonally. You can adjust
               the width and height of the rectangle as long as you hold down the
               cursor.
            
- Release the cursor to anchor the second
               vertex.
               The rectangle is drawn
                  on the image.
