To map triangle RST onto triangle VWX, the transformations described in the problem state that triangle RST can be rotated about point S and then shifted down and to the left.
- Rotation: You can rotate triangle RST around point S to align it with triangle VWX.
- Translation: After rotation, you can translate (shift) the triangle down and to the left to fit triangle VWX perfectly.
Therefore, the correct transformation(s) that can be used to map △RST onto △VWX is:
Rotation, then translation.
