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]$\triangle A'B'C$[/tex] is a rotation. When [tex]$\triangle A'B'C$[/tex] is reflected across the line [tex]$x=-2$[/tex] to form [tex]$\triangle A^ B^ C^*$[/tex], vertex B' of [tex]$\triangle A^{\circ}B^{\circ}C^{\circ}$[/tex] will have the same coordinates as [tex]$B'$[/tex].
