Geometry

Question Analysis:
This question tests understanding of corresponding angles in congruent triangles.

Key Concept Explanation:
Congruent triangles have equal corresponding angles.
The naming order defines which angles match.

Step-by-Step Solution:
⊿XYZ ≅ ⊿PQR implies:
X ↔ P, Y ↔ Q, Z ↔ R.
Thus, ∠Y ≅ ∠Q.
Given ∠Y = 40°, ∠Q = 40°.

Option Analysis:
A: Correct (direct correspondence).
B/C: Incorrect (assume unrelated ...
