draw ab 9.2 cm
draw ax downwards
intersect ax 3 times...a1 a2 a3
join a3b
Measuring the arc at a3 construct a corresponding arc at a2.
join a2 to b1 on ab
u'll find that ab'/b'b = 2/3.
bisect ab' using compass.
u'll get point a'.
now measure.
when u measure u should get aa'=a'b'=b'b=3.2
and ab'= 6.2
if u did, then there's your answer!!
