Answer:
corresponding
Explanation:
The correct question is
If two triangles are congruent, then the six _____parts are congruent
we know that
If two triangles are congruent, then the corresponding angles and the corresponding sides are congruent
Example
If triangle ABC is congruent to triangle DEF
∠A ≅ ∠D
∠B ≅ ∠E
∠C ≅ ∠F
AB ≅ DE
BC ≅ EF
AC ≅ DF
therefore
If two triangles are congruent, then the six corresponding parts are congruent
