| | center of dilation | Explanation:
dilation (math.) Streckung {f}
http://www.dict.cc/?s=Streckung
A dilation is a transformation (notation ) that produces an image that is the same shape as the original, but is a different size. A dilation stretches or shrinks the original figure.
The description of a dilation includes the scale factor (or ratio) and the center of the dilation. The center of dilation is a fixed point in the plane about which all points are expanded or contracted. It is the only invariant point under a dilation.
