This diagram shows a pre-image △ABC, and its image, △A′′B′′C′′, after a series of transformations. Select from the drop-down menus to correctly complete the statements. △ABC is Choose... (reflected across y axis, reflected across y=x line, rotated 180 degrees about the origin) to become △A′B′C′.
Then △A′B′C′ is Choose... (reflected across x axis, translated 3 units down, rotated 90 about the origin) to become △A′′B′′C′′ .
Because the transformations are Choose... (rigid, not rigid) , the pre-image and image are Choose... (congruent, not congruent) .
