This is an example of a rotation. A rotation is a type of translation that rotates each point in a center point by the same given degree. In my rotation I rotated each point 90 degrees round the origin counterclockwise. You can form a rotated object using a protractor and patty paper. For example if you wanted to rotate an image 45 degrees first you make a 45 degree angle on a piece of patty paper. Then you put the vertex of the angle on the center point with one leg on the first image's point. You then press hardly on the other leg's end point with your pencil and flip up the patty paper. You should see a light dot. That is your rotated point repeat these steps for each point and you will get your image. You can check your rotated image by measuring each point making sure it is all rotated the degree you want it to.
