Is  $\Delta ABC$  similar to  $\Delta DEF$  ? Why or why not?

• No, because not all the angles are congruent

• Yes, because the angles are congruent and the sides are proportional

• Yes, because the angles are close enough and the sides are proportional

• We cannot tell because third side is not given
