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 is not congruent to trapezoid a′b′c′d′ because there is no sequence of rigid motions that maps trapezoid abcd to trapezoid a′b′c′d′ . b) trapezoid abcd is congruent to trapezoid a′b′c′d′ because you can map trapezoid abcd to trapezoid a′b′c′d′ by reflecting it across the x-axis and then across the y-axis, which is a sequence of rigid motions. c) trapezoid abcd is congruent to trapezoid a′b′c′d′ because you can map trapezoid abcd to trapezoid a′b′c′d′ by reflecting it across the x-axis and then rotating it 90° clockwise, which is a sequence of rigid motions. d) trapezoid abcd is congruent to trapezoid a′b′c′d′ because you can map trapezoid abcd to trapezoid a′b′c′d′ by rotating it 180° about the origin and then translating it 4 units left, which is a sequence of rigid motions.
