Final answer:
In congruent triangles DEF and XYZ, every corresponding pair of sides and angles is congruent, which includes all three sides and all three angles of the triangles.
Step-by-step explanation:
The statement DEF = XYZ implies that triangle DEF is congruent to triangle XYZ. When two triangles are congruent, it means that all corresponding sides and angles are equal in measurement. Thus, each pair of corresponding sides and angles in the two triangles are congruent. This includes:
- Side DE is congruent to side XY
- Side EF is congruent to side YZ
- Side FD is congruent to side ZX
- Angle D is congruent to angle X
- Angle E is congruent to angle Y
- Angle F is congruent to angle Z
To answer the student's question directly, every pair of corresponding parts (sides and angles) between triangles DEF and XYZ are congruent.
