"The two figures are congruent because rigid motions are used to map Figure 1 onto Figure 2.
"Angle corresponding to ∠J: ∠V
1) Counting the lengths of each side, (by the length of x, and the displacement in y) we can state that both figures are congruent.
Note that this is a rough way of measuring. Just considering the "rise/run" in each line segment.
2) Also, we can state that angle J is corresponding to angle ∠V in figure 2.
3) Thus we can answer that as:
"The two figures are congruent because rigid motions are used to map Figure 1 onto Figure 2.
"Angle corresponding to ∠J: ∠V
