transformations

Quadrilateral QRST is rotated 180° about the origin, resulting in quadrilateral Q'R'S'T' as seen in the figure.
Which series of transformations would have the same result as the above transformation

• A reflection across the x-axis and then a reflection across the y-axis
• A translation 8 units to the left and then a reflection across the y-axis
• a 90° clockwise rotation about the origin and then a reflection across the x-axis
• A translation 8 units to the right and then a 90° clockwise rotation about the origin.
