Apolygon is shown on the graph:
what effect will a translation 3 units down and 2 units left have on the polygon? be sure to address how it could impact the angles, side lengths, and congruency between the original pre-image and the image.

When you carry your jewelry box or your phone 3 floors down
and 2 miles to the left, the angles and side-lengths don't change,
and it still looks exactly the same as it did before you picked it up
and moved it.

Translation can't change angles or lengths.  And if those don't
change, then the later shape is congruent to the earlier shape.
