Step 2: Draw an acute ∠CBA on one side of the line AB.
Step 3: Mark points B1,B2,B3,B4,B5,B6,B7 on ray BC
such that BB1=B1B2=B2B3=B3B4=B4B5=B5B6=B6B7.
Step 4: Join B7 to A.
Step 5: Draw lines B1I,B2H,B3G,B4F,B5E and B6D parallel to B7A and let them intersect AB in points I,H,G,F,E and D respectively.
Points D,E,F,G,H and I divide the segment AB in 7 equal parts.
