To determine which triangle congruence criterion to use, I would need more specific information about the triangles, such as the lengths of their sides or the measures of their angles. However, here are some common triangle congruence criteria:
1. **SSS (Side-Side-Side)**: If all three sides of one triangle are equal to the three sides of another triangle, then the triangles are congruent.
2. **SAS (Side-Angle-Side)**: If two sides of one triangle are equal to two sides of another triangle, and the included angle is also equal, then the triangles are congruent.
3. **ASA (Angle-Side-Angle)**: If two angles and the included side of one triangle are equal to two angles and the included side of another triangle, then the triangles are congruent.
4. **AAS (Angle-Angle-Side)**: If two angles and a non-included side of one triangle are equal to two angles and the corresponding non-included side of another triangle, then the triangles are congruent.
5. **HL (Hypotenuse-Leg)**: This is specific to right triangles. If the hypotenuse and one leg of one right triangle are equal to the hypotenuse and one leg of another right triangle, then the triangles are congruent.
After identifying which criterion applies, you would then list the congruent angles.
For example, if we determined that two triangles are congruent by the ASA criterion, you would list the angles that correspond to the congruence. For instance, you could write:
- Triangle ABC and Triangle DEF are congruent by ASA.
- Congruent angles: ∠A ≅ ∠D and ∠B ≅ ∠E.

If the triangles are congruent by the ASA (Angle-Side-Angle) criterion, then you have two angles and the included side of one triangle corresponding to two angles and the included side of the other triangle.
Let’s denote the two triangles as Triangle ABC and Triangle DEF, where:
- ∠A ≅ ∠D (the first angle of Triangle ABC is congruent to the first angle of Triangle DEF)
- ∠B ≅ ∠E (the second angle of Triangle ABC is congruent to the second angle of Triangle DEF)
- The included side AB is equal to DE (the side between the angles).
Thus, the congruent angles are:
- ∠A ≅ ∠D
- ∠B ≅ ∠E
Additionally, since the sum of the angles in a triangle is always 180 degrees, you can find that:
- ∠C ≅ ∠F (the third angles of both triangles will be congruent as well).
So, in summary, all of the congruent angles are:
- ∠A ≅ ∠D
- ∠B ≅ ∠E
- ∠C ≅ ∠F
If you have particular angle measurements or specific names for the triangles, please let me know, and I can provide more tailored information!
