Any image in a plane could be altered by using different
operations, or transformations. Here are the most common types:
Translation is when we slide a figure in any direction.
Reflection is when we flip a figure over a line.
Rotation is when we rotate a figure a certain degree around a
point.
Dilation is when we enlarge or reduce a figure.
