Which statement best explains whether △PQR is congruent to △XYZ?

△PQR is congruent to △XYZ because △PQR can be mapped to △XYZ by a rotation of 180° about the origin.

△PQR is congruent to △XYZ because △PQR can be mapped to △XYZ by a translation 5 units down followed by a reflection across the y-axis.

△PQR is not congruent to △XYZ because there is no sequence of rigid motions that maps △PQR to △XYZ.

△PQR is congruent to △XYZ because △PQR can be mapped to △XYZ by a reflection across the y-axis followed by a reflection across the x-axis.

    Two geometic shapes are congruent if one can be mapped to the other only by using rigid motions: translations and rigid rotations. The third statement is the only one that is true for any triangles â-łPQR and â-łXYZ, in whichever position they are.
