The graph shows quadrilaterals Q and R. y 8 6 4- 21 2 4 6 8 -8 -6 -4 -2 -2 -41 R -61 -8 Which statement justifies whether or not the two quadrilaterals are congruent? A. Yes, because R is the result of reflecting across the x-axis. OB. Yes, because R is the result of reflecting across the line y = x. O C. No, because R can only be obtained from Q by a series of rigid transformations. D. No, because R cannot be obtained from Q by a series of rotations and translations. OE. Yes, because R is the result of rotating Q by 90° counter-clockwise about the origin.
