On the segment AB 23 cm long, points C and D were marked so that AC = 15 cm, DB = 12 cm. What is the length of the segment CD?

Let us define the sequence in which the points are located on the segment AB.

Since CB = AB – AC = 23 – 15 = 8 cm. CB <DB (8 <12).

We get that the points are located as follows: A – D – C – B.

Then, the length of the segment CD is equal to: CD = AC – DB.

CD = AC – CB = 15 – 12 = 3 cm.

Answer: the length of the CD segment is 3 cm.
