Question
The points $(3,0)$ and $(-1,0)$ are invariant points under reflection in the line $L _1$, while the points $(0,-3)$ and $(0,1)$ are invariant points under reflection in the line $L _2$.
(a) Name the lines $L _1$ and $L _2$
(b) Write down the images of the points $P (3,4)$ and $Q (-5,-2)$ on reflection in $L _1$. Name the images as $P ^{\prime}$ and $Q ^{\prime}$ respectively.
(c) Write down the images of $P$ and $Q$ on reflection in $L _2$. Name the images as $P ^{\prime \prime}$ and $Q ^{\prime \prime}$ respectively.
(d) State or describe a single transformation that maps $P ^{\prime}$ onto $P ^{\prime \prime}$.
