Answer 1

A.

Explanation:

Answer 2

Option A is correct.

Use HL to prove two triangles are congruent.

Explanation:

Labelled the given diagram:

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

`AB \cong DE` [leg] [Given]

`AC \cong DF` [Hypotenuse side] [Given]

`\angle B = \angle D= 90^(\circ)`

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
`\cong` ΔDEF.

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