Definitions: Enlargement: sometimes called scaling or dilation, is a kind of transformation that changes the size of an object. The image created is similar to the object. Reduction: to make smaller Isometry: Isometries include rotation, translation, reflection, glides, and the identity map Glide Reflection: the combination of a reflection in a line and a translation along that line.
Real World Applications:
We use Dilations and Isometries as pixels for a bigger picture. Artists when making their album covers use a lot of dilation, and Tessalations.
