translation only
rotation only
rotation, then reflection
reflection, then translation

To determine which transformation(s) can map Triangle PQR onto Triangle STU, we first need to consider the given transformations:
1. **Reflection**: Triangle PQR is reflected across QR.
2. **Translation**: Triangle is then shifted up and to the right.
Given that transformation involves reflecting and then translating, the correct answer would be:
**Reflection, then translation.**
This means that Triangle PQR is first reflected across QR, and then it is translated (shifted) to position it over Triangle STU.
