Question: If triangle PQR is similar to triangle STU, and the sides of triangle PQR are 3, 4, and 5, what are the lengths of the corresponding sides of triangle STU if the ratio is 2:1?
Options:
Correct Answer: 6, 8, 10
Solution:
If the ratio is 2:1, then the sides of triangle STU will be 3*2, 4*2, and 5*2, which are 6, 8, and 10.
