If D is the midpoint of the segment

AC

and C is the midpoint of segment

DB

, what is the length of the segment

AB

, if AC = 3 cm.

Answer provided by our tutors

Since AC is 3cm, then AD and DC are 1.5cm segments.  Since C is the midpoint of segment DB, then CB is 1.5cm. 

So AD, DC and CB are each 1.5cm segments. 

1.5+1.5+1.5
