Step1: Fórmula de reflexión en $x = a$
Para un punto $(x,y)$ reflejado en la recta $x = a$, la nueva coordenada $x'=2a - x$ y $y'=y$.
Step2: Fórmula de reflexión en $y = a$
Para un punto $(x,y)$ reflejado en la recta $y = a$, la nueva coordenada $y'=2a - y$ y $x'=x$.
Step3: Fórmula de reflexión en $y = x$
Para un punto $(x,y)$ reflejado en $y = x$, las coordenadas se intercambian: $x'=y$ y $y'=x$.
Step4: Fórmula de reflexión en $y=-x$
Para un punto $(x,y)$ reflejado en $y = -x$, $x'=-y$ y $y'=-x$.
