The DC segment is larger than the BD segment.

Therefore, point C stands after points B and D on a straight line.

1) Let point B first lie on the straight line, then D and C.

Then the segment ВС = BD + DC = 17 + 25 = 42 cm.

2) Let point D first lie on the line, then B and C.

Then the segment ВС = DC – BD = 25 – 17 = 8 cm.
