2 Answer

  • The answer is option 2. It was a reflection over the line y=x.
  • Answer:

    2) reflection

    Step-by-step explanation:

    Let's list down the coordinates of the triangle ABC and the triangle A'B'C'

    A = (0, -4)

    B = (3, -4)

    C = (3, 0)

    A' = (-4, 0)

    B' = (-4, 3)

    C' = (0, 3)

    Here the transformation is a reflection and (x, y) -----> (y, x)

    So, the triangle ABC reflected over the line x = y and got the image of triangle A'B'C'

    Therefore, the answer is 2) reflection
