Which series of transformations will map the trapezoid onto itself? reflection over the x-axis, then a rotation 180° counterclockwise about the origin
reflection over the y-axis, then a rotation 180° counterclockwise about the origin
reflection over the line y = x, then a rotation 90° counterclockwise about the point (0,2)
O reflection over the line y = 2, then a rotation 90° counterclockwise about the point (0, 2)
