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
.
