Question

I need help I don’t understand at all ?

Answer 1

its the 3rd option

Explanation:

first of all AA means angle-angle which means we are using their angles to compare them

second, those lines on the sides are only there to tell you they are in the exact same angle, and the two boxes on the bottom show that the angle of both triangles is 90° therefore they are the same

Answer 2
