  Moroccan Geometry: S7 HW: 12-fold with ball (Tanashri bl kora) (تناشرث بل كورة) 1.  Draw a circle the size of the page. This will be divided into 12ths.  Note:   The ratio of the circle diameter to the height and width of the finished design is roughly 5:3.  For 12"x18"  paper, i f you wish to make the finished design larger so that it takes up nearly the size of the page, you'll need to t ake an extra sheet and divide it into two pieces along the horizontal, then tape the pieces to the top and bottom of the page as shown. A circle with a 9" radius will take up the entire 18" page, and will yield a finished design approximately 18"x3/5, or 10.8", leaving margins of 1.1" on the top and bottom. To yield a larger design, you'll need to tape 1" strips to each side of the page, which would allow for up to a 20" diameter (10" radius), and a finished design of 20"  x 3/5, or 12", which would take up the entire page with no ...

  Moroccan Geometry: S7 Class: 12-fold with almond (Tanashri bl looza) (تناشرث بل لوزة) 1. Draw a circle the size of the page. This will be divided into 12ths.  Note: If you wish to make the finished design larger so that it takes up the size of the page, the ratio of the circle diameter to the finished height and width of the design should be about 5:3. So if you are working with 12"x18"  paper, then attach 2 sheets so that they meet in the middle of the finished page, and if you want the design to be about 11.5" square, then make the diameter of the 11.5x5/3, or about 19.17",  thus the radius will be about 9.6". For this, you'll need to use the beam attachment to your compass. Divide this circle into 4ths by first drawing the horizontal by measuring along the sides of the page with a ruler, then find the vertical by the arc method, using a second compass with a larger radius and the point at 3:00 and 9:00, forming intersecting arcs to define the vertical....
