d. If the hypotenuse and an acute angle of a right triangle are congruent to the corresponding parts of another right triangle, then the triangles are congruent.
Step-by-step explanation:
The hypotenuse, acute angle, and right angle form a AAS triple. When these are congruent between two right triangles, the triangles are congruent by the AAS postulate.
