A.

Step-by-step explanation:

Option A is correct.

Use HL to prove two triangles are congruent.

Step-by-step explanation:

Labelled the given diagram:

In triangle ABC and triangle DEF as shown in figure below.

  [leg]                 [Given]

   [Hypotenuse side]      [Given]

HL(Hypotenuse -Leg) postulates states that if the hypotenuse and one leg of a right triangle are congruent to the hypotenuse and one leg of another right triangle, then the triangles are congruent.

Then, by HL postulates;

ΔABC ΔDEF.

Therefore, the method you use to prove the two triangle congruent is, HL.
