In triangle ABC, parallel to side AC, three straight lines are drawn, which divided side AB into segments of 3.5 cm. Into what segments was side BC divided if its length is 18 cm?

Construct a triangle ABC and draw parallel lines to the AC side. The intersection points will be designated by the letters K, K1, M, M1, H, H1.

The AB side is divided into four equal segments (AK = KM = MH = HB). The same can be said about the BC side (BH1 = H1M1 = M1K1 = K1C).

Let’s find into which segments the side of the aircraft was divided, knowing that its length is 18 cm.

BH1 = H1M1 = M1K1 = K1C = 18/4 = 4.5 cm.

Answer: The BC side is divided into 4 equal segments of 4.5 cm.
