Question

When doing a transformation (specifically rotation and reflection), how do you do arrow notation if the images aren't on a coordinate plane?

Answer 1

What do you mean 'aren't on the coordinate plane'?

Answer 2

They are on a blank plane without coordinates or anything. Just a flag-shape ABCD and its image A'B'C'D. Something like this

Answer 3

If there isn't a coordinate system, then you get to make up your own.

Answer 4

It's a \(90^\circ \) rotation (counterclockwise). \[
(x,y) \to (-y, x)
\]

Answer 6

Ok thanks!
