HL means hypotenuse leg. Since you know the triangles are right triangles, and the hypotenuses are congruent, you need a statement that states that two legs are congruent.

OpenStudy (mathstudent55):

You can eliminate choices A and B because they deal with angles, and we need sides. Now look at choice C. Are AC and DC legs? What about choice D. Are AC and BD legs?

OpenStudy (anonymous):

would it be D?

OpenStudy (mathstudent55):

Is BD the leg of a triangle?

OpenStudy (mathstudent55):

AC and DC are legs of the two triangles. BD is not a leg.

OpenStudy (mathstudent55):

That means the answer is not D.

OpenStudy (anonymous):

so c than?

I wrote above you can eliminate A and B. Then I told you the answer is not D. That leaves only C. You are correct.
