Answer

Yes. ΔDEF can be mapped to ΔRPQ by a reflection across the x-axis followed by a translation 2 units left.

Yes. ΔDEF can be mapped to ΔRPQ by a 180° rotation about the origin followed by a translation 2 units down.

No. ΔDEF cannot be mapped to ΔRPQ by a rigid transformation or combination of rigid transformations.
