1. Visualization with GInMA in geometry teaching Vladimir Shelomovskii, Svetlana Nosulya Russia

2. GInMA in geometry GInMA for teaching provides visualization and deeper understanding of mathematics. GInMA for research broadens opportunities to perform interactive research in the field of mathematics.

3. GInMA idea We have made DGS and Library of more than 800 examples and samples. Users start from PDF, explore geometric drafts in shareware, make and save files in payware.

4. Installation, shareware To make geometric drafts alive, install the program from the website deoma-cmd.ru. deoma-cmd.ru Click Geometry button on Main page, or GInMA button on the panel to download GInMA software. Shareware is free Use "GInMA installation guide"

5. GInMA support, GInMA Library On Geometry page use the link "GInMA brief user manual" which helps you to use images in GInMA files and control them. On Geometry page use the link "GInMA User Manual" which helps you to make complicated constructions on your own. GInMA Library includes more than 800 interactive drafts. Click on the figures and investigate interactive constructions.

6. Active point, point with parents, a segment, directed segment, a ray, a line, perpendicular lines, a circle, an arc, the sign of the angle, a triangle, a polygon, a plane, normal plane, a sphere, a cylinder, a cone, text GInMA: Basic construction

7. Use the adequate formula to create a point,directed segment, a segment, a ray, a line, a circle, a plane, a sphere, a curve (function), truncated sphere, truncated cylinder, a surface. GInMA: Analytic construction

8. Use the transformation to create homothetic, centrosymmetry, axial symmetry, plane symmetry, translation, inversion. GInMA: Transformations

14. GInMA for teaching GInMA Library shows: Orthotomics Pedal surface Caustics Evolute

15. GInMA for teaching Visualization of 3D motion to develop spatial imagination. Moving of the object on the screen is organized in a comfortable way.

16. GInMA for teaching Samples of polyhedrons Samples allow you to supplement the images in the drafts of the set and to create your own interactive constructions. You may save your constructions after purchasing the set. Regular Tetrahedron Regular triangular pyramid Cube Prism, right triangle in base Truncated pyramid
