Final answer:
A sequence of transformations comprising a reflection followed by a translation maps triangle AABC to triangle SABC, indicating that both reflection and translation occur without rotation or dilation.
Step-by-step explanation:
The sequence of transformations that maps triangle AABC to triangle SABC involves a reflection followed by a translation. Reflection is a transformation that creates a mirror image of a shape over a line, known as the line of reflection. Translation is a type of transformation that slides every point of a shape a constant distance in a specified direction. The naming of the transformed figure SABC indicates that the sequence does not include rotation or dilation, thereby eliminating those options. Therefore, the transformations that have occurred are a reflection followed by a translation.
