Answer:
So, the signs of the coordinates for triangle F'G'H after the reflection are: Positive x-coordinates and Negative y-coordinates.
Explanation:
When a shape is reflected across the X-axis, the signs of its y-coordinates change while the signs of its X-coordinates remain the same. In the case of triangle F'G'H:
The x-coordinates will remain positive.
The y-coordinates will change from positive to negative. Hopefully, I'm right
