Rotations
A type of transformation that takes each point in a figure and rotates (Turns/Spins) it a certain number of degrees around a given point
2
Rotations in the real world.
An example of rotation would be looking at a clock. This is an example of rotation because the clock hands rotate in a clockwise motion around a single, fixed point.

Movement
Rotations are defined by the way they turn. One way they turn is described in two directions Clockwise (CW) or Counterclockwise (CCW).
5
Movement 2
Rotations are also measured by the distance they turn around a circle. This is measured in degrees. A full circle is 360 degrees.
6
Congruent Figures
Rotations change the orientation of a figure, but the object remains the same size and shape (congruent).
We also refer to this as a Rigid Transformation.
