Answer: OPTION D.
Step-by-step explanation:
The S-S-S Postulate is also known as "Side-Side-Side Postulate". This states that when three sides of two triangles are equal, then the triangles are congruent.
The HL Theorem is also called "The Hypotenuse Leg Theorem" and states that when we have two right triangles (which are triangles that have an angle that measures 90 degrees) and their hypotenuses are congruent and one leg of both triangles are congruent too, then the right triangles are congruent.
Then, if the hypotenuses and one of the legs are congruent, the other leg of one of these triangles is also congruent to corresponding leg of the other triangle.
Therefore, we can conclude that the HL Theorem is a special case of the S-S-S Postulate.
