Answer:
HL
Explanation:
These two triangles are congruent by the HL Congruence Theorem.
The HL Congruence Theorem states that two triangles are congruent if they meet the following requirements
- They must be right triangles.
- Their hypotenuse must be congruent.
- One leg is congruent.
For this triangle:
- In this case, we see that both triangles are right triangles.
- The hypotenuse is congruent, since the hypotenuse for both triangles is the same line.
- Finally, we see that side AC is congruent to side CD.
This triangle meets all the HL Congruence Theorem requirements!
