Transformations - Rotations
We turn our papers when drawing rotation to predict where and how the rotation will turn out. This is because when you turn the paper, the original figure will be in the same position that the rotated figure will be. A rotated figure does not change in size, shape, or location. A rotated figure differs from a reflection because a reflection is when you make a figure on the opposite side of a line of symmetry. And a rotation is when you rotate a figure around a center point. If you rotate a figure 90 degrees clockwise and then 90 degrees counterclockwise, it will end up in the same position that it started. The same thing will happen if you rotate the figure 360 degrees counterclockwise, the only difference is that it will be upside down. The difference between rotating a figure clockwise or counter clock wise is that counterclockwise goes in the opposite direction.
