Transfö app for iPhone and iPad

A transformation geometry app. You are asked to plot points, write coordinates, translate, rotate, reflect and resize triangles. Your results are saved on the iPad and to an online database. You can work offline without losing your results.
Teachers can see their students results.

1. Plotting: plot points on the Cartesian plane
2. Coordinates: indicate coordinates of points on the Cartesian plane
3. Translations: move triangles by dragging, or using arrow buttons.
4. Reflections I: reflect triangles across lines using reflection tool.
5. Rotations I: rotate triangles around the origin using rotation tool.
6. Dilatations I: stretch or shrink triangles to or from the origin using dilatation tool.
7. Reflections II: reflect triangles across lines by plotting points.
8. Rotations II: rotate triangles around the origin by plotting points.
9. Dilatations II: stretch or shrink triangles to or from the origin by plotting points.
