Answer 2

What do you think?

Answer 3

either C or D @iGreen

Answer 4

Nice job eliminating the first two choices.

Answer 5

When we reflect something across the line, it's a mirror image of it, and it doesn't look exactly the same.

Answer 6

So what do you think?

Answer 7

C? @iGreen

Answer 8

No, I said it doesn't look exactly the same, but it does in the picture.

Just imagine it being flipped over the line, if you do that it won't be the same.

Answer 9

Answer 11

We can just move it up 4 units and it'll be on top of it.
