In the adjacent figure PQ and RS are two mirrors placed parallel to each other. An incident ray $$\overrightarrow{AB}$$ strikes the mirror PQ at B, the reflected ray moves along the path $$\overrightarrow{BC}$$ and strikes the mirror RS at C and again reflected back along $$\overrightarrow{CD}$$. Prove that AB || CD.
