Question

δabc ≅ δfed. use the diagrams to identify corresponding parts. side ac corresponds to side. angle bac corresponds to ang. def efd fde

Explanation:

Step1: Recall congruent - triangle property

When \(\triangle ABC\cong\triangle FED\), the order of the vertices gives the correspondence.

Step2: Find corresponding side

The first - and third - named vertices of the first triangle correspond to the first - and third - named vertices of the second triangle for sides. So, side \(AC\) corresponds to side \(FD\).

Step3: Find corresponding angle

The first - named vertices of the angle in \(\triangle ABC\) and \(\triangle FED\) give the corresponding angle. So, \(\angle BAC\) corresponds to \(\angle EFD\).

Answer:

Side \(AC\) corresponds to side \(FD\). Angle \(BAC\) corresponds to angle \(EFD\).
