# First reflection, then rotation and finally translation

Geometry Level pending

The point P(1,2,3) is reflected in the xy-plane. If the image of point P is Q, then OQ (where O is the origin) is rotated by $$180^0$$ in the plane containing OQ and the x-axis about O to produce R. Finally, the point R is translated by 5 units in the positive direction of y-axis to produce the point S. The sum of the coordinates of S is...
