Use rigid motions to explain whether the triangles in the figure are congruent. Be sure to describe specific rigid motions in your explanation.

Answer:
There are 2 steps:
1. 90° counterclockwise rotation about the origin
2. Translation downward 2 units
Step-by-step explanation:
1. 90° counterclockwise rotation about the origin = (x, y) to (-y, x),
D moves from (-2, 4) to (-4, -2)
W moves from (-1, 2) to (-2, -1)
P moves from (3, 3) to (-3, 3)
2. Translation downward 2 units = (x, y) to (x, y-2),
D moves from (-4, -2) to (-4, -4) = M
W moves from (-2, -1) to (-2, -3) = J
P moves from (-3, 3) to (-3, 1) = S
