The point A' is the image of A by applying a rotation of 90° counterclockwise applied on the latter. The angle of rotation is + 90°.
How to determine the nature of the rotation of a given point
Rigid transformations are transformations applied on geometric loci such that Euclidean distances are conserved. Based on the image attached below, we conclude that point A' is generated by rotating 90° the point A counterclockwise with respect to point O. Rotation is a kind of rigid transformation.
