The drawing shows a top view of a square room. One wall is missing and the other three are each mirrors. From point P in the center of the open side, a laser is fired, with the intent of hitting a small target located at the center of one wall. Identify vector in whose direction the laser can be fired and score a hit, assuming that the light does not strike any mirror more than one.
