Trapezoid QRST undergoes a series of transformations to form trapezoid Q'R'S'T'.

Which statement is true?

• The trapezoids are congruent because there is a set of rigid motions that maps trapezoid QRST onto trapezoid Q'R'S'T'

• The trapezoids are congruent because there is not a set of rigid motions that maps trapezoid QRST onto trapezoid Q'R'S'T'

• The trapezoids are not congruent because there is a set of rigid motions that maps trapezoid QRST onto trapezoid Q'R'S'T'

• The trapezoids are not congruent because there is not a set of rigid motions that maps trapezoid QRST onto trapezoid Q'R'S'T'
