To determine how many units quadrilateral ABCD has shifted, we would typically need the coordinates of the points before and after the shift. Since I cannot see or analyze the image directly, I can guide you on how to calculate the shift.
1. **Identify Original Coordinates**: If you have the original coordinates of quadrilateral ABCD, note them down.
2. **Identify New Coordinates**: Next, note the new coordinates of quadrilateral ABCD after the shift.
3. **Calculate Shift**:
- **Horizontal Shift**: Subtract the x-coordinate of a point in the original position from the corresponding x-coordinate in the new position to find how many units it has shifted to the left or right.
\[
\text{Horizontal Shift} = \text{New X} - \text{Original X}
\]
If the result is negative, it means the shift is to the left. If positive, it is to the right.
- **Vertical Shift**: Similarly, subtract the y-coordinate of a point in the original position from the corresponding y-coordinate in the new position to find how many units it has shifted up or down.
\[
\text{Vertical Shift} = \text{New Y} - \text{Original Y}
\]
If the result is negative, it means the shift is down. If positive, it is up.
4. **Express the Result**: Once you've calculated the shifts, you can fill in the blank in your statement.
Since I cannot see the image or coordinates, I suggest you follow this process with the specific coordinates you have.
