Answer:
F(-3,-1)
Explanation:
Notice that there was applied rigid transformation to get the triangle FGH, this means the size and shape won't change.
Also, triangle FGH is like a reflection of triangle ABC accros the line y = -1, and it's being shifted 1 unit rightwards.
Applying these transformations, the point F must be at (-3,-1).
Additionally, remember that rigid transformation won't change the size or shape of the figure, which means both triangles are congruent.
