The single transformation one could per form on the figure to get the final image is a rotation of 270 degrees counterclockwise around the origin.
The original figure cordinates (x,y)
A Reflection of the figure at the right across the y-axis, gives a coordinate(-x, y)
The y axis will remain the same. While the x axis will change sign.
A rotation of 180 degrees around the origin around the origin will have the coordinates (-x, -y)
The x and y axis changes signs.
When we carry out both transformation, the coordinates we get represent a transformation of 270 degrees counterclockwise around the ori
