Answer:HL, ASA, SSS, ASA
Explanation:
1. HL because the hypotenuse are equal by the reflexive property and the at least one pair of legs are congruent. Also the interior angles are congruent.
2. ASA because the interior angles are both congruent and the included side is congruent by the reflexive property.
3. SSS because the corresponding sides are congruent and the line is congruent by reflexive property so all the sides are congruent.
4. ASA because the interior angles are congruent and the other pair of angles are also congruent because they are verticle angles. The including sides are also congruent so therefore angle-side-angle.
