Congruent triangles have congruent corresponding parts. When writing the mathematical notation for congruent triangles, you chould place the conruent angles in the same position (first letter, second letter or third letter in notation of triangle).
In your case, if △AYH≅△ZRL, then
- ∠A≅∠Z;
- ∠Y≅∠R;
- ∠H≅∠L
and sides adjacent to congruent angles should be congruent:
- AY≅ZR;
- YH≅RL;
- AH≅ZL.
