Question

which angle is congruent to angle j? *
△def ≅ △kji
angle d
angle f
angle e

Explanation:

Step1: Recall congruent triangle properties

In congruent triangles $\triangle DEF\cong\triangle KJI$, corresponding angles are congruent.

Step2: Identify corresponding angles

The order of the letters in the congruence statement $\triangle DEF\cong\triangle KJI$ gives the correspondence: $D$ corresponds to $K$, $E$ corresponds to $J$, and $F$ corresponds to $I$.

Answer:

Angle E
