A reflection of the pink triangle is shown. Which transformation makes this reflection?
A) (x', y') = (y, x)
B) (x', y') = (x, -y)
C) (x', y') = (-x, y)
D) (x', y') = (-x, -y)
If these two figures are similar, what is the measure of angle B?
A) 35°
B) 70°
C) 95°
D) 130°
Find the coordinates of the vertices of the figure after the given transformation.

A) U'(0, 5), P'(-1, 0), R'(3, -1), D'(3, 2)
B) U'(2, -4), P'(1, 1), R'(5, 2), D'(5, -1)
C) U'(-1, 3), P'(-2, 2), R'(2, 3), D'(2, 0)
D) U'(-4, -3), P'(-5, 2), R'(-1, 3), D'(-1, 0)
