Identify the transformation that maps the figure onto itself

A) rotate 180 clockwise about (8, 4) and reflect across the Line y-8

B) rotate 180, clockwise about (8,4) and reflect across the Line x=8

C) rotate 180 clockwise about (7,1) and reflect across the Line y 1
D) rotate 180 clockwise about (7,1) and reflect across the line x-8

Respuesta :

The only sensible choice is ...
   B) rotate 180° clockwise about (8,4) and reflect across the Line x=8.

_____
All the other choices appear to have typographical errors (and they don't work).

The point (8,4) is the center of rotational symmetry for the figure, and the line x=8 is a line of symmetry. Either transformation will map the figure to itself, as will both transformations together.
