A dilation is just a shrinking or expanding of a particular polygon. It keeps the same shape and angle measurements, but the lengths of the sides are different.
A scale factor is how much a polygon is dilated. The scale factor of this polygon and its dilated shape is how much the original shape is multiplied by to get the dilated shape. For example;
The scale factor here is 2.
A scale factor can be any number like 0.5 (half) to 100 (100 times the original).
