Question: Two transversals S and T cut a set of distinct parallel lines. S cuts the parallel lines in points A, B, C, D and T cuts the parallel lines in points E, F, G and H, respectively. If AB = 4, CD = 3 and EF = 12, then what is the length of GH?
Options:
A) 4
B) 6
C) 8
D) 9
Show Answer
Answer:
Correct Answer: D
Solution:
- From figure,
Let GH = x
By proportionality law, $ \frac{AB}{CD}=\frac{EF}{GH} $
$ \Rightarrow $ $ \frac{4}{3}=\frac{12}{x} $
$ \Rightarrow $ $ x=3\times 3=9 $
