As shown in the graph, ΔGHI ≅ ΔG'H'I', since this is a vertical shift, and ΔG'H'I' ≅ ΔG''H''I'', since this is a horizontal shift. What translation can we use to directly show that triangles GHI and G''H''I'' are congruent?

(x, y) → (x + 2, y + 2)

(x, y) → (x + 3, y - 4)

(x, y) → (x - 3, y + 1)

(x, y) → (x + 4, y - 5)
