Preimage And Image Coordinates. Identify preimage and image coordinates. For clockwise rotations use the negative value of θ.
In general when reflecting a point in the origin if the coordinate of the preimage is x y then the coordinate of the reflected image is x y when reflecting a point across any line just keep this mind. X x 8 3 2 5 8 3 2 8 5 3 x 6 2 search. Kason11wd found this answer helpful.

For example the square abcd when translated four units right becomes square a b c d. In general when reflecting a point in the origin if the coordinate of the preimage is x y then the coordinate of the reflected image is x y when reflecting a point across any line just keep this mind.
