It is known that AC = 8 cm, BC = 2 cm, BD = 6 cm Find the length of the segment AD.

It is known that AC = 8 cm, BC = 2 cm, BD = 6 cm, which means that point B is between points A and C, and point C is between points B and D.

There are two options for solving this problem.

Option 1:

1) СD = ВD – ВС;

CD = 6 – 2 = 4 (cm) – the length of the CD segment;

2) AD = AC + CD;

AD = 8 + 4 = 12 (cm) – the length of the segment AD.

Option 2:

1) AB = AC – BC;

AB = 8 – 2 = 6 (cm) – length of the segment AB;

2) AD = AB + BD;

AD = 6 + 6 = 12 (cm) – the length of the segment AD.

Answer: 12 cm length of the segment AD.
