What set of reflections would carry parallelogram abcd onto itself?

a) x-axis, y=x, x-axis, y=x

b) y=x, x-axis, y=x, y-axis

c) y-axis, x-axis, y-axis

d) x-axis, y-axis, y-axis

B) y=x, x-axis, y=x, y-axis
the y=x will flip the figure within the same quadrant the rule (x,y) to (y,x) changing A (-1,-2) to A' (-2,-1). The x axis changes(x,y) to (-x,y)  or A'' (2,-1) y=x chages  the points using the rule (x,y) to (y,x) it to A'''(-1,2). the y axis changes it back to the original A(-1,-2) bu the rule (x,y) to (x,-y).

127 millimeters is the answer
