Question

(05.08A) Triangle ABC is transformed to similar triangle A'B'C' below:65.4ДА3Ло0What is the scale factor of dilation?оу

Answer 1

REmember that

If two triangles are similar, then the ratio of its corresponding sides is proportional, and this ratio is called the scale factor

so

In this problem

scale factor=B'C'/BC

we have

B'C'=1

BC=2

therefore

scale factor=1/2
