If you translate the triangle one lattice to the left, can you show the positions of the three vertices of the triangle with pairs of numbers

If you translate the triangle one lattice to the left, can you show the positions of the three vertices of the triangle with pairs of numbers

If the original vertices of the triangle are (a, b), (C, d), (E, f), then the three vertices after translation are (A-1, b) (C-1, d) (E-1, f)
