Determine if you can use the HL ! Congruence Theorem to prove triangle ABC cong triangle DCB If not, tell what else you need to know

Answer: Yes you can use the HL theorem
Explanation:
HL = hypotenuse leg
The tickmarks tell us about the congruent hypotenuse sides. This takes care of the "H" from "HL".
The "L" portion is because BC = BC (reflexive property) which are the congruent legs.
So we have enough info to use the HL theorem to prove the triangles are congruent.
Note: The HL theorem only works for right triangles.
