Huh? You already said that |AB|=4cm
To construct the figure,
bisect a 60° angle to get angle A.
Mark B where an arc of radius 4 intersects one side of angle A.
C lies on a circle C<sub><sub>B</sub></sub> of radius 5 with center at B.
D lies on a circle C<sub><sub>A</sub></sub> of radius 5 with center at A.
So, CD is a segment joining any two suitable points on C<sub><sub>A</sub></sub> and C<sub><sub>B</sub></sub>

oops. C<sub><sub>A</sub></sub> has radius 3.5
