To determine the quadrant of triangle ΔLOW after the specified reflections, we need to understand how reflections across the axes affect the coordinates of points.
1. **Reflection across the y-axis**: When a point (x, y) is reflected across the y-axis, its new coordinates become (-x, y). This means the x-coordinate changes sign while the y-coordinate remains the same.
2. **Reflection across the x-axis**: When a point (x, y) is reflected across the x-axis, its new coordinates become (x, -y). This means the y-coordinate changes sign while the x-coordinate remains the same.
Now, follow these steps:
1. Take any point (x, y) from triangle ΔLOW.
2. Reflect across the y-axis: This transforms the point to (-x, y).
3. Now reflect this new point across the x-axis: This transforms it to (-x, -y).
These transformations result in a new point (-x, -y).
Next, we need to determine the quadrant of the resulting point (-x, -y). The quadrants are defined as follows:
- Quadrant I: (x, y) where both x and y are positive.
- Quadrant II: (x, y) where x is negative and y is positive.
- Quadrant III: (x, y) where both x and y are negative.
- Quadrant IV: (x, y) where x is positive and y is negative.
Since both x and y are changed to their negatives in the final point (-x, -y), if the original point (x, y) was in Quadrant I, it would move to Quadrant III after the reflections because both coordinates become negative.
Therefore, after reflecting triangle ΔLOW across the y-axis and then across the x-axis, it will be in:
**Quadrant III.**
1. **Reflection across the y-axis**: When a point (x, y) is reflected across the y-axis, its new coordinates become (-x, y). This means the x-coordinate changes sign while the y-coordinate remains the same.
2. **Reflection across the x-axis**: When a point (x, y) is reflected across the x-axis, its new coordinates become (x, -y). This means the y-coordinate changes sign while the x-coordinate remains the same.
Now, follow these steps:
1. Take any point (x, y) from triangle ΔLOW.
2. Reflect across the y-axis: This transforms the point to (-x, y).
3. Now reflect this new point across the x-axis: This transforms it to (-x, -y).
These transformations result in a new point (-x, -y).
Next, we need to determine the quadrant of the resulting point (-x, -y). The quadrants are defined as follows:
- Quadrant I: (x, y) where both x and y are positive.
- Quadrant II: (x, y) where x is negative and y is positive.
- Quadrant III: (x, y) where both x and y are negative.
- Quadrant IV: (x, y) where x is positive and y is negative.
Since both x and y are changed to their negatives in the final point (-x, -y), if the original point (x, y) was in Quadrant I, it would move to Quadrant III after the reflections because both coordinates become negative.
Therefore, after reflecting triangle ΔLOW across the y-axis and then across the x-axis, it will be in:
**Quadrant III.**
