The rule (x, y) — (-x,-y) maps triangle RST to triangle R'S'T'. Which statement correctly describes the relationship between triangle RST and triangle R'S'T'

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)"
