Question

match ∠b to its corresponding part. △abc ≅ △def ∠f ∠e ∠g

Explanation:

Step1: Understand congruent triangles

When \(\triangle ABC\cong\triangle DEF\), the corresponding parts (angles and sides) are equal. The order of the letters in the congruence statement \(\triangle ABC\cong\triangle DEF\) gives the correspondence. That is, \(A\) corresponds to \(D\), \(B\) corresponds to \(E\), and \(C\) corresponds to \(F\).

Step2: Identify the corresponding angle

For angles, \(\angle B\) in \(\triangle ABC\) corresponds to \(\angle E\) in \(\triangle DEF\) because of the order of the congruence \(\triangle ABC\cong\triangle DEF\).

Answer:

\(\angle E\)
