50 points , and brainliest 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 ( reflected across the y axis , reflected across the line y=x ,or rotated 90 degrees counterclockwise about the origin ) to become △a′b′c′ . then △a′b′c′ is across the x axix, translated 4 units down , or rotated 180 degrees about the origin )to become △a′′b′′c′′ . because the transformations (both rigid or not  both rigid) , the pre-image and image are or not congruent ) .
