Some examples from historical mathematical textbook with using GeoGebra

摘要

In our contribution we would like to show how is possible to use GeoGebra in some historical — mathematical textbook. We show some examples from the textbook Václav Posejpal: Aritmetika pre ústavy učitel'ské (Arithmetic for Teachers' Institutes) with using GeoGebra. This textbook is from Library of Teachers Academy in Spišská Kapitula and we have Slovak translations from this textbook, which was made by Vladimír Hapala. We use exercise book from this textbook. GeoGebra can help teachers to use the time more effectively and support visualisation of the solutions of the examples.
