Triangle A prime, B prime, C prime is, graphed. A prime (negative 4, comma negative 2), B prime (negative 2, comma negative 6), and C prime (negative 5, comma negative 4). was reflected across the , and then that result was rotated clockwise about the origin to result in , shown at right. Find the coordinates of points , , and of the original triangle.  

To undo the transformation, rotate counter-clockwise then reflect the result across the .
