Answer:
A
Explanation:
Using the information given to you, mark the corresponding congruent parts and angles. The markings will show congruent 90 degree angles in each triangle and congruent legs of the triangle. Since the triangles overlap, their hypotenuses are the same side and therefore congruent by the reflexive property. This means the triangles are congruent by a hypotenuse, leg and right angle. This is known as HL.
