Final answer:
To determine the ratio (n) of one side of triangle ADEF to a corresponding side of triangle ABC, measure a side of ADEF, compare it with the corresponding side of ABC, and express this as a fraction. If ADEF's side is 6 units and ABC's is 9 units, the ratio is 2/3.
Step-by-step explanation:
To find the ratio (n) of one side of triangle ADEF to the corresponding side of triangle ABC, we first need to measure the length of a side in triangle ADEF. Then, we compare it to the corresponding side in triangle ABC. The ratio is the length of the side in ADEF divided by the length of the corresponding side in ABC, written as a fraction.
For example, if we measure side AD in triangle ADEF and find that it is 6 units long, and the corresponding side AB in triangle ABC is 9 units long, then the ratio (n) would be 6/9, which simplifies to 2/3.
The correct option based on our measurement would be:
