"Transformations"- Rotations
We turn our papers when drawing rotations because when we rotate the paper, It shows us what quadrant the figure will be. This is predicting where and how the rotation will turn out because it tells us what quadrant the new figure will be in and the coordinates for that figure. A rotated figure doesn't changes in size or shape, but it does change in location. A rotated figure is different from a reflection because a rotated figure is when a shape is rotated either clockwise or counterclockwise, and reflection is a figure that is being flipped over by any line of symmetry. If we rotate a figure 90 degrees clockwise and then 90 degrees counterclockwise, then the figure will stay in the same location. If we rotate a figure 360 degrees counterclockwise, then the figure will also be in the same location. The difference between rotating a figure clockwise and counterclockwise is that the figure will be in a different location.
