Rotation

Rotations can be clockwise or counterclockwise. A rotation can be turned or rotated by degrees such as 90 degrees 180 and 360 degress. But every rotation has a centre of rotation. The centre of rotation is mostly located on the the origin.



The origin is located in the middle of the vertical and horizontal number line. You can also call it (0,0) in the coordinate grid.
