Anhand der in Kasten A abgebildeten Konstruktionen und der zugehörigen Arbeitsaufträge können die Schülerinnen und Schüler dieses Funktionsprinzip erkunden und gleichzeitig ihr Verständnis zu zentrischen Streckungen und den Strahlensätzen vertiefen.
Liegen die Dreiecke auf derselben Seite des Streckungszentrums, so kann man vergrößern und verkleinern, ohne dass das Bild um 180° gedreht ist.

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.
