A transformation is a movement of some sort. Four basic transformations are:
a) Translation
A translation is the direct movement of a selected area, or a slide.
b) Rotation
Rotation is exactly what its name says, a rotation, or a turn. However, you can rotate across any point you choose.
c) Reflection
A reflection maps the picture on the left of the axis to the right. The axis can also be the axis of symmetry in a symmetrical shape.
d) Dilation/Homothety
A dilation, also known as homothety, is a re-sizing of a picture by a scale factor x. 2 scale factor would make the picture twice as big, 1/2 as a scale factor would make the picture half sized.
