polygon abcde is the first in a pattern for a high school art project. the polygon is transformed so that the image of a' is at (−2, 4) and the image of d' is at (−1, 2). which transformation can be used to show that abcde and its image are congruent? rotate abcde 90° counterclockwise. translate abcde left 4 units and down 2 units. reflect abcde over the y-axis. rotate abcde 90° clockwise.
