Final Answer:
1. Congruent
2. Similar
3. Neither
4. Neither
5. Congruent
6. Congruent
7. AB ↔ MN, BC ↔ NO, AC ↔ MO; ∠A ↔ ∠M, ∠B ↔ ∠N, ∠C ↔ ∠O
8. JK ↔ TU, KL ↔ UV, JL ↔ TV; ∠J ↔ ∠T, ∠K ↔ ∠U, ∠L ↔ ∠V
9. DE ↔ GH, EF ↔ HI, DF ↔ GI; ∠D ↔ ∠G, ∠E ↔ ∠H, ∠F ↔ ∠I
10. C (∠J)
11. Yes, because all three corresponding angles are congruent and the triangles are labeled with matching vertices (A↔T, B↔U, C↔V), so △ABC ≅ △TUV by ASA or AAS (since two angles and the included/non-included side would match in congruence criteria — but here, since all angles match and the correspondence is given, and triangles with all angles equal *and* same size (implied by congruence symbol ≅) are congruent).
