What is the relationship between the segments PQ and P’Q’
cupoosta [38]

Answer:

\frac{PQ}{P'Q'}=2.5

Step-by-step explanation:

we know that

If two figures are similar, then the ratio of its corresponding sides is equal

In this problem Triangles OQP and OQ'P' are similar by AA Similarity Postulate

so

\frac{PQ}{P'Q'}=\frac{OP}{OP'}

we have

OP=12-2=10\ units

OP'=6-2=4\ units

substitute

\frac{PQ}{P'Q'}=\frac{10}{4}=2.5
