△abc is mapped to △a′b′c′ using the rule (x, y)→(−x, −y) followed by (x, y)→(x, −y) . which statement correctly describes the relationship between △abc and △a′b′c′ ? a. △abc is congruent to △a′b′c′ because the rules represent a reflection followed by a rotation, which is a sequence of rigid motions. b. △abc is congruent to △a′b′c′ because the rules represent a rotation followed by a reflection, which is a sequence of rigid motions. c. △abc is not congruent to △a′b′c′ because the rules do not represent a sequence of rigid motions. d. △abc is congruent to △a′b′c′ because the rules represent a reflection followed by a reflection, which is a sequence of rigid motions.
