Compassionate

A Geometric Construction Using Ruler and Compass, the important position that it had in the curriculum of both secondary and high schools in Romania. This is unfortunate because, in order to be well assimilated, geometry requires the student to extensively exercise problem solving skills and invest time in understanding the fundamental truths that lie subtly hidden behind a geometric figure.

Using Duality in Studying Homographic Recurrences,ications, for students-whose mathematical knowledge is now being formed — problems in this subject can cause many surprises and difficulties, as well as they can be fertile ground for their first investigations.

放逐

Throttle

A Geometric Construction Using Ruler and Compass,e not only a very good knowledge of basic results in geometry but also special skills and cleverness. Regretably in the last decades geometry has lost the important position that it had in the curriculum of both secondary and high schools in Romania. This is unfortunate because, in order to be well

The First Decimal of Some Irrational Numbers,will also try to show how important the algorithmicity and the generality are among the attributes of a creative solving method. These are both essential qualities, that can suggest many directions of exploring around the given problem.
