Question

select which shortcut can be used to prove this pair of triangles congruent. if no method applies, choose “none.”

Explanation:

Step1: Identify right - angled triangles

The triangles have a right - angle (marked with the square symbol).

Step2: Observe equal sides

The hypotenuses are equal (the long sides) and one of the legs is equal (the sides marked with one tick). In right - angled triangles, when the hypotenuse and one leg of one right - triangle are congruent to the hypotenuse and one leg of another right - triangle, we can use the HL (Hypotenuse - Leg) congruence criterion.

Answer:

HL (Hypotenuse - Leg)
