Answer with explanation:
It is given that , two triangles
Either→ ΔR ST ≅ ΔW X Y or ΔR ST ~ ΔW X Y.
That is two triangles are either similar or congruent.
So, if two triangles are congruent , their corresponding parts ,that is angles and sides are congruent.
Also, if two triangles are Similar, then their corresponding angles are equal , and corresponding sides are proportional.
So, corresponding part of ,∠T is ∠Y whether the triangle is congruent or similar.
∠ T = ∠Y
