The coordinates of the vertices of trapezoid abcd are a (2,6), b (5,6), c (7,1), and d (-1,1). the coordinates of the vertices of trapezoid a'b'c'd' are a' (-6, -2),b' (-6, -5), c' (-1, -7), and d' (-1, 1). which statement correctly describes the relationship between trapezoid abcd and trapezoid a'b'c'd' ? a. trapezoid abcd ≅ trapezoid a'b'c'd' you can reflect trapezoid abcd across the x-axis and then across the y-axis. b. trapezoid abcd ≅ trapezoid a'b'c'd' you can rotate trapezoid abcd 180°about the origin and then translating it 4 units left. c. trapezoid abcd ≅ trapezoid a'b'c'd' you can reflect trapezoid abcd across the x-axis and then rotating it 90°clockwise.
