Question

Trapezoid ABCD is congruent to trapezoid A" B" C" D" .

Which sequence of transformations could have been used to transform trapezoid ABCD to produce trapezoid A" B" C" D" ?




A.
Trapezoid ABCD was translated 7 units up and then 12 units left.

B.
Trapezoid ABCD was reflected across the x-axis and then across the y-axis.

C.
Trapezoid ABCD was reflected across the y-axis and then translated 7 units up.

D.
Trapezoid ABCD was reflected across the y-axis and then across the x-axis.

Answer 2

Answer 3

I think C or D

Answer 4

Ok, if it were reflected across the x-axis, then the figure would be upside down

Answer 5

ok

Answer 6

so A? @sleepyjess

Answer 7

Well, that is for the x-axis, so now it is between A and D. Reflection across the y-axis means it is flipped (not the best drawing again, just pretend the shapes are congruent)

Answer 8

so B

Answer 9

@sleepyjess

Answer 10

Nope, it can't be reflected across the x-axis

Answer 11

so C

Answer 12

Yep

Answer 13

Thanks ^_^
