Which series of transformations shows that pentagon a is congruent to pentagon b? a. reflect pentagon a over the y-axis and translate it 2 units to the left and 8 units up. b. rotate pentagon a 90° counterclockwise about the origin, reflect it over the x-axis, and translate it 8 units to the right and 1 unit up. c. reflect pentagon a over the y-axis, rotate it 180° clockwise about the origin, and translate it 3 units up. d. rotate pentagon a 90° clockwise about the point (3, 1), reflect it over the x-axis, and translate it 3 units to the left. res
