This diagram shows a pre-image triangle ABC, and its image triangle A”B”C”, after a series of transformations. select from the drop-dow menus to correctly complete the statements. 1. triangle ABC is A. reflected across the y-axis B. reflected across the line y = x C. rotated 90 degrees counterclockwise about the origin
2. to become triangle A’B’C’ is A. reflected across the x-axis
B. translated 4 units down
C. rotated 180 degrees about the origin
3. to become triangle A”B”C”. because the transformations are A. both rigid B. not both rigid
4.the pre-image and image are A. congruent B. not congruent
