The triangles shown at right are similar.
What is the ratio of side length
to side length ?
Use a ratio to compare the perimeters of
and . How is the perimeter ratio related to the side length ratio?
In part (a), you found that the zoom factor between the two triangles is
Now use this information to find the perimeters of each triangle, then find the ratio between them.
If you have not already done so, find the length of
