The two triangles created by the diagonal of the parallelogram are congruent. Recall that the opposite sides of a parallelogram are congruent.

A parallelogram is shown. It is folded from one point to another to form 2 triangles.

Which transformation(s) could map one triangle to the other?

translation

A 180° rotation (a half‑turn) about the midpoint of the diagonals maps one triangle to the other: it sends A↔C and B↔D. So a rotation (half‑turn) carries one triangle onto the other.

(If you must pick from the given choices — which do not include “rotation” alone — pick “rotation and translation,” but note that a single 180° rotation about the diagonal midpoint already suffices.)
