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

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
