To find the ratio between ΔDEF and ΔABC, we can use the corresponding side lengths of the triangles.
In ΔABC, AC measures 16 and AB measures 22.
In ΔDEF, FD measures 8 and DE measures 11.
Since the triangles are similar, we can set up the following proportion:
AC/FD = AB/DE
Plugging in the values, we get:
16/8 = 22/11
Simplifying the left side, we get:
2 = 22/11
Multiplying both sides by 11, we get:
22 = 22
Therefore, the ratio between ΔDEF and ΔABC is 1:1, or 1/1 as a fraction in simplest form.
