A sequence of transformations maps [tex]\( \triangle ABC \)[/tex] onto [tex]\( \triangle A^{\circ}B^{\circ}C^{\circ} \)[/tex].
The type of transformation that maps [tex]\( \triangle ABC \)[/tex] onto [tex]\( \triangle A^{\prime}B^{\prime}C \)[/tex] is a __________.
When [tex]\( \triangle A^{\prime}B^{\prime}C \)[/tex] is reflected across the line [tex]\( x = -2 \)[/tex] to form [tex]\( \triangle A^\ \textless \ em\ \textgreater \ B^\ \textless \ /em\ \textgreater \ C^* \)[/tex], vertex __________ of [tex]\( \triangle A^{\circ}B^{\circ}C^{\circ} \)[/tex] will have the same coordinates as [tex]\( B^{\prime} \)[/tex].
