A Transformation is any movement of a geometric figure.
Above, we have a geometric figure graphed on a plane. The first type of transformation is called a translation:
A Translation is a movement of a figure without turning it.
Here, the figure has been moved to a new location.
In a Reflection, a figure is “flipped” over a line of symmetry.
Here, the figure has been flipped over a line of symmetry.
In a Rotation, a figure is rotated around a fixed point.
Here, the figure has been rotated around the red fixed point.
