a sequence of transformations that proves congruence between shape i and shape ii by mapping shape i onto shape ii is a reflection across the y-axis, followed by a (blank) , and then a translation 1 unit down.
alternatively, a sequence of transformations that proves congruence between shape ii and shape i by mapping shape ii onto shape i is a reflection of shape ii about the x-axis, followed by a (blank) , and then a translation 1 unit left.

blank 1:
a reflection across the x- axis
b 90 degree clockwise rotation about the origin
c 90 degree counterclockwise rotation about the origin
d 180 degree rotation about the origin

blank 2:
a reflection across the y- axis
b 90 degree clockwise rotation about the origin
c 90 degree counterclockwise rotation about the origin
d 180 degree rotation about the origin
