  Adv S6 class Mtemen Bil Kora (8-fold with ball) (متمن بل كرة) Notes on the basic pattern: The pattern consists of a main circle that is then inscribed by a square. The square is then subdivided in quarters, and these quarters are divided into eighths. A circle is drawn in each quarter. These circles are already divided in eighths, and the divider is used to find the distance between sixteenths. One point of the divider is then placed at the point where the verticle of each quarter meets the top of the square (and the circle within the square), and the other point marks the radius of a smaller circle to be drawn from the center of each quarter. These four smaller circles should also just touch the large circle along its circumference, at 45°, 135°, 225°, and 315°, or π/4, 3π/4, 5π/4, and 7π/4. These smaller circles are then divided into sixteenths (using dividers), and the points that mark the sixteenths where they flank each of the previously drawn vertical, horizontal, and diagonal

  Adv S5 HW: Al-Ankaboutiya (The Spiderweb) Part A: Draw the circles 1.  define the center of the page, and from there, draw the center circle. It’s circumference, on a 12”x18” page, will be about 7.75” (7 3/4”), so set the compass to 3.875” (3 7/8”). Set the compass aside to use again in step 4. 2.  define the horizontal through the circle. Only where the horizontal crosses the circle does in need to be marked. 3. from the horizontal crossings, set another compass with a larger radius to create two crossing arcs above and below the circle. Connect these crossings through the center, again only marking the points where the vertical crosses the circle 4. Now setting the compass point at 12:00, 3:00, 6:00 and 9:00 markings, using the original compass from step 1, draw 2 arcs from each points, to define the points where the diagonals go. Connect these diagonals, again, only marking where the line crosses the circle. Now the circle has been divided into eighths 5. Divide the circle into si
