If triangle ABC is similar to triangle DEF with AB corresponding to DE and a scale factor of 2, what is DE when AB = 3?

Explanation:
Two similar triangles have corresponding sides in a constant ratio, the scale factor, which tells you how much to multiply lengths from one triangle to get the other. Since AB corresponds to DE and the scale factor is 2, DE is 2 times AB. With AB = 3, DE = 2 × 3 = 6.
