You want to prove that $${{ABCD}}$$ and $${{A'B'C'D'}}$$ are congruent by using a translation. Explain how you could translate $${{ABCD}}$$ onto $${{A'B'C'D'}}$$ so that they overlap perfectly. Be specific and use the coordinate plane as a reference.
Translate Figure $${ABC}$$ 3 units to the right and 2 units up. Name and label the new figure.
FIgure 1 is congruent to Figure 2.
Which statement demonstrates the congruency between the two figures?

Two figures are shown in the coordinate plane. Alex thinks that the two figures are congruent because Figure $${QRS}$$ could be translated 5 units to the left and 2 units down to map to Figure $${Q'R'S'}$$.
