Question

In the figure, the horizontal lines are parallel and AB = BC = CD. Find JM.

A.15
B.10
C.5
D. 20

Answer 1

By the transversal theorem, if segments on a transversal cut by parallel lines are equal, then similar segments cut by the same parallel lines on another transversal are also equal.

Therefore

JK=KL=LM=5

=>

JM=3*5=15
