"Transformations - Rotations"

We turn our paper when drawing rotations because for we could get a better prediction of the shape and for what number quadrant that the shape go to, For example, if the figure is in quadrant 2 at 180 degrees clockwise it will be in quadrant 4.The rotation will turn out good because when you play around with the paper you will know that spinning the paper had helped a lot.No it does not only change the location of the figure because it is going clockwise or counterclockwise by 90, 180, or 360.Rotation is different from reflection because reflection just reflect on the shape,For example if the figure is at quadrant 1 reflect on the x-axis it will be under the original shape and rotation is when you move by a degrees reflection does not move by a degrees. When you rotate a figure 90 degrees clockwise and the then rotate it again 90 degrees counterclockwise it will be in the same spot you was at before.If you rotate a figure 360 degrees you did not rotate nothing because 360 degrees is the same spot you at.The different of rotating a figure 180 counterclockwise or clockwise is that counterclockwise it is the opposite of clockwise and plus it is going back words and clockwise it is going forward just like a regular clock goes but they will be in the same location counterclockwise or clockwise it does not matter it will be in the same spot but only for 180 degrees. For example, if you at quadrant one if you move counterclockwise 180 degrees it will be at quadrant three but if go clockwise 180 degrees it will be at quadrant three it will be in the same location only 180 degrees but 90 degrees will be different!!!!!!!!!!!!!!!!!!!
