Step-by-step explanation:
that is really easy - you only need to look up what the acronyms mean ...
we have 2 angles and their connecting side to be congruent.
so, it is the Angle Side Angle (ASA) criterion.
D is the right answer.
the others would be
SAS - side angle side. it means 2 sides and their enclosed angle are congruent.
SSS - side side side. all 3 sides are congruent.
HL - Hypotenuse leg. it means that if the hypotenuse and leg of one right triangle are congruent to the hypotenuse and leg of another right triangle, then the two triangles are congruent. essentially this is a SSA (side side angle) criterion.
