Rotation is a turn around a center point; a rotation preserves the size and shape (congruent images), but not the orientation. To solve this worksheet, students should have to ability to visualize the rotation. They can use the given buttons “⟲90°” and “⟳90°” to see the visuals on the coordinate plane. For example, if the original figure is the same as its image after pressing “⟲90°” button twice it means the answer can be 90° counterclockwise or 270° clockwise.
