Question

∆DEF is similar to ∆ABC and the scale factor from ∆ABC to ∆DEF is 2. In ∆ABC, the largest angle measures 82º. Which measurements below could represent the largest angle in ∆DEF? Select all that apply.

Answer 1

B

Explanation:

the scale factor of 2 means the sides of Δ DEF are twice those of Δ ABC.

However, corresponding angles remain congruent , then

largest angle in Δ DEF is also 82°
