Hello there,

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 reflected across the line y = x

to become △A′B′C′ . Then △A′B′C′ is reflected across the x-axis

△A′′B′′C′′ . Because the transformations are both rigid

, the pre-image and image are congruent.
