Answer:
true statements:
- A'B' is parallel to C'D'
- the area of parallelogram ABCD is equal to area of A'B'C'D'
- the perimeter of ABCD is equal to the perimeter of A'B'C'D'
btw just so u understand the work i have shown above:
- the green parallelogram is the original one before any work was done
- the blue one was after it was reflected across the y-axis
- and the brown one was after the blue parallelogram was reflected across the x-axis
sorry if that was a confusion... i forgot to add it above im really sorry
but apart from that, hope u understand and get an A :))
