Geometrical analogies in mathematics lessons

A typical form of thinking to approach problem solutions humanly is thinking in analogous structures. Therefore school, especially mathematical lessons should help to form and to develop corresponding heuristic abilities of the pupils. In the contribution, a summary of possibilities of mathematics lessons regarding this shall particularly be conveyed from the view of geometry lessons in different age groups, being supposed to be exemplarily illustrated introducing character and object of making analogies as an example. Different kinds of analogous conclusions are described exemplarily with some examples for different geometrical contents and didactic situations.
