# DG Interactive Geometry Package

## Overview and purpose

DG Interactive Geometry package is created for computer support of school geometry course. DG is a computer
environment for experiments in plane geometry.

DG is used by teachers of geometry and students of 7-9 grades at the lessons of geometry. The goal
of the package is to give students an ability to explore geometry by carrying out computer experiments.
DG
can also be used to illustrate problems and facts in plane geometry, to create and use visual interactive
learning materials. It is aimed to help teachers of geometry and their students to make geometry
learning process more visual, comprehensive and comfortable.

DG is a model of euclidean geometry in plane: geometric objects and relationships (dependencies) between
them.

DG can be used in education process by teachers of geometry, students and everybody else who is interested
in geometry to learn, explore, investigate and experiment, insight hypothesis and visually check their
plausibility.

DG was the first educational software in Ukraine to be certified by the Ukrainian
Scientific Center for State Registration and Certification of Information Technologies and approved
by the Ministry of Education and Science to be used in ukrainian schools.
