If \[\Delta ABC\cong \Delta FED\]under the correspondence \[ABC\leftrightarrow FED,\] write all the corresponding congruent parts of the triangles.

Answer:

                Corresponding vertices: A and F; B and E; C and D. Corresponding sides: \[\overline{\text{AB}}\] and \[\overline{\text{FE}}\]; \[\overline{\text{BC}}\] and \[\overline{\text{ED}}\]; \[\overline{\text{CA}}\] and \[\overline{\text{DF}}\]. Corresponding angles: \[\angle A\] and \[\angle F;\angle B\]  and \[\angle E;\angle C\] and  \[\angle D\]
