Ideas on how to use the corner command[edit]

Place objects exactly on the screen[edit]

Sometimes you might have trouble finding some objects when you open your GeoGebra file on an different computer. The reason is usually that the resolution of the display is different from the one of your home computer. But there are some possibilities to avoid disappearing objects:

  1. Place the objects close to the upper left corner. As this corner is saved in the file for the position of the visible graphic-area, the objects should be always visible.
  2. Use the Corner command to calculate the position of an object relative to the corners of the Graphics View. For more information look at this brief tutorial.
