3-8, Rotations (8.G.1 , 8.G.2, 8.G.3, and 8.G.4 Extended)
A rotation is a transformation that turns a figure about a fixed point called the center of rotation. A figure has rotational symmetry if it can be rotated 180 degrees or less and exactly matches its original figure.
Rotations change the position of a figure but not its size or shape. The angle of rotation is the number of degrees the figure rotates. A complete rotation is 360 degrees.
