To determine the series of transformations that move the rectangle in Quadrant IV to the rectangle in Quadrant II and show that they are congruent, we need to consider the positions of the rectangles in their respective quadrants.
- A rectangle in Quadrant IV has its vertices with coordinates that are usually positive for \( x \) and negative for \( y \).
- A rectangle in Quadrant II has its vertices with coordinates that are negative for \( x \) and positive for \( y \).
A possible series of transformations might involve the following:
1. **Rotation**: If we rotate the rectangle in Quadrant IV by 180 degrees around the origin, it will move to Quadrant II. Rotation alone achieves moving the rectangle directly from Quadrant IV to Quadrant II.
2. **Reflection**: Alternatively, we can reflect the rectangle across the y-axis first, which will move it to Quadrant III (still negative for \( x \) and negative for \( y \)), and then rotate it by 180 degrees to move it to Quadrant II.
3. **Translation**: A translation alone would not work because it would maintain the orientation and size but would not change the quadrant from IV to II without further adjustments.
When considering the options provided, it looks like the most straightforward answer would involve using rotation. Therefore, transforming from Quadrant IV to Quadrant II could be achieved with a simple rotation.
Given the options, the most relevant transformation sequence to show that the rectangles are congruent is:
**a. rotation, then reflection**
However, if strictly considering a sequence of transformations to move from one location to the other with a single rotation, the initial transformation is most directly described as:
**c. rotation then translation**
Though the reflection may meet certain conditions in other scenarios, the direct transformation for moving rectangles congruently from Quadrant IV to Quadrant II can be interpreted best with the above.
