Answer:
The options are missing, but i will answer the general statements about this type of transformation.
A transformation of the type (x, y) ----> (-x, -y) can be written in two forms:
> A rotation of 180° over the point (0, 0)
> A reflection over the line x = y.
Then the statements can be something like:
"The triangle R'S'T' is a reflection over the line x = y of the triangle RST"
Or
"The triangle R'S'T' is the rotation of 180° of the trianlgle RST about the point (0,0)"
