- Q1Which of the following is not true of a trapezoid that has been reflected across the x-axis?The new trapezoid is the same shape as the original trapezoid.The new trapezoid is the same size as the original trapezoid.The x-coordinates of the new trapezoid are the same as the x-coordinates of the original trapezoid.The new trapezoid is in the same orientation (position) as the original trapezoid.120sEditDelete
