Question

Which sequence of transformations does NOT give the image A'B'C'D' from the preimage ABCD?
1.a rotation 90° counterclockwise about the origin
2.a reflection across the line y = x followed by a reflection across the y-axis
3.a reflection across the y-axis followed by a reflection across the line y = -x
4.a rotation 270° counterclockwise about the origin followed by a reflection across the line y = -x
5.a rotation 90° clockwise about the origin, then a reflection across the y-axis, then a reflection across the x-axis
does anyone know the answer :) ♥
