graph them on graph paper
1,15 1,0 12,0 12,15 connect these points together. next graph these points and connect them 5,14 5,11 1,11 1,10 5,10 5,5 6,5 6,10 9,10 9,11 6,11 6,14. then connect these points 3,4 3,2 then graph these points 4,4 4,2 then connect these 3,3 4,3 then connect these 6,4 6,2 6,4. graph and connect these 7,4 7,2 8,2 then connect these 8,4 8.5,3 9,48.5,3 8.5,2 then connect these 3,2 3,0 4,0 4,1 3,1 4,1 4,2 3,2 then connect these 5,2 5,0 then connect these 6,2 6,0 7,0 7,1 6,1 7,1 7,2 6,2 then connect these 8,2 8,0 9,0 then connect these 9,0 9,1 9,2 then connect these 9,0 10,0 then connect these 9,1 10,1 then connect these 9,2 10,2
