Is ΔDEF≅ΔD′E′F′​? Explain.

Yes, because reflections across the​ y-axis and the​ x-axis, followed by a translation of 6 units ​left, map ΔDEF to ΔD′E′F′.

Yes, because reflections across the​ y-axis and the​ x-axis, followed by a translation of 6 units ​left, map ΔDEF to ΔD′E′F′.

Yes, because a reflection across the​ x-axis, followed by a translation of 6 units left and 3 units ​up, maps ΔDEF to ΔD′E′F′.

No, because a sequence of transformations does not map ΔDEF to ΔD′E′F′.

Is ABCDE≅​VWXYZ? Explain.

Yes, because a rotation of 180° about the​ origin, followed by translations of 1 unit up and 1 unit right maps ABCDE to VWXYZ.

Yes, because a rotation of 180° about the​ origin, followed by translations of 1 unit left and 1 unit down maps ABCDE to VWXYZ.

Yes, because translations of 1 unit up and 1 unit​ left, followed by a reflection across the​ x-axis maps ABCDE to VWXYZ.

No, because there is no sequence of transformations that maps ABCDE directly onto VWXYZ.
