Which sequence of transformations will verify that △EFG and △E'F'G' are congruent? A) △EFG is moved onto △E'F'G' after rotating 180° counterclockwise around the origin, and then reflecting across the x-axis. B) △EFG is moved onto △E'F'G' after rotating 180° counterclockwise around the origin, and then reflecting across the y-axis. C) △EFG is moved onto △E'F'G' after rotating 270° counterclockwise around the origin, and then reflecting across the x-axis. D) △EFG is moved onto △E'F'G' after rotating 270° counterclockwise around the origin, and then reflecting across the y-axis.
pls HELP
