Question
How do you use the Hypotenuse-Leg (HL) Theorem?
If you have an acute triangle where the hypotenuses are congruent and one other corresponding side congruent (also known as the leg)
If you have a right triangle where the hypotenuses are congruent and one other corresponding side congruent (also known as the leg)
If you have two corresponding sides in each triangles congruent and a pair of corresponding angles not included congruent
If you have an acute triangle where the hypotenuses are congruent and one other corresponding side congruent (also known as the leg)
If you have a right triangle where the hypotenuses are congruent and one other corresponding side congruent (also known as the leg)
If you have two corresponding sides in each triangles congruent and a pair of corresponding angles not included congruent

The Hypotenuse-Leg (HL) Theorem is a specific criterion used to prove the congruence of two right triangles. Here are the conditions under which you can apply the HL Theorem:
1. **Right Angles**: Both triangles must be right triangles.
2. **Congruent Hypotenuses**: The hypotenuses of both triangles must be congruent (equal in length).
3. **Congruent Legs**: One of the legs (the two sides that form the right angle) in each triangle must be congruent.
Under these conditions, if you establish that the hypotenuses are congruent and one leg is congruent, the two triangles can be concluded to be congruent.
### Important Points:
- The HL theorem applies **only** to right triangles, so it does not apply to acute triangles or other configurations.
- The condition of having a congruent leg does not mean both legs need to be congruent—just one matching leg alongside the congruent hypotenuses suffices.
### Scenarios You Mentioned:
1. **Acute Triangle (hypotenuses congruent + one leg congruent)**: The HL theorem does **not** apply. The theorem only pertains to right triangles.
2. **Right Triangle (hypotenuses congruent + one leg congruent)**: You can use the HL Theorem in this scenario to conclude that the two right triangles are congruent.
3. **Two corresponding sides congruent + not included congruent angle**: This does not fit the HL Theorem. This scenario does not establish congruence by itself, as it does not involve the specific conditions needed for the HL theorem.
### Conclusion:
The HL Theorem can only be used in scenarios involving right triangles with one leg and the hypotenuse being congruent. For other types of triangles or congruence criteria, different methods or theorems (like SSS, SAS, or ASA) would apply.
