Options Menu

Global options may be changed in the menu Options.

Note: To change object settings, please use the Context Menu and Properties Dialog.

Algebra

Point Capturing

This menu item determines if the point capturing is Off or if points are captured by the grid (item Snap to Grid) or constrained on the grid (item Fixed to Grid)

Note: Option Automatic turns the point capturing On when the grid or the coordinate system are shown and turns it Off if they are hidden.

Angle Unit

This menu item determines whether angles are displayed in Degree (°) or Radians (rad).

Note: Input is always possible in both ways (degree and radian).

Rounding

This menu item allows you to set the number of decimal places or significant figures displayed on screen.

Continuity

GeoGebra allows you to turn the continuity heuristic On or Off in the Options menu. The software uses a near‐to‐heuristic to keep moving intersection points (e. g., line‐conic, conic-conic) close to their old positions and avoid jumping intersection points.

Note: By default this heuristic is turned off. For user defined tools continuity is always turned off as well.

Point Style

This menu item determines how points are displayed by default, i.e. as ● dots, ○ circles, x crosses and other styles.

Checkbox Size

This menu item allows you to set the size of checkboxes to Regular or Large.

Note: If you are using GeoGebra as a presentation tool or are working with an interactive

whiteboard, setting the checkbox size to Large might make it easier for you to use

checkboxes.

Right Angle Style

Determines whether right angles are displayed as a rectangle □, a dot •, or like all other angles (Off).

This menu item determines whether coordinates of points are displayed as A = (x, y) or A(x | y).

Labeling

You can specify whether the label of a newly created object should be shown or not. You can choose between the settings All New Objects, No New Objects, New Points Only, and Automatic.

Note: The setting Automatic shows the labels of newly created objects if the Algebra View is shown.

Font Size

This menu item determines the font size for labels and text in points (pt).

Note: If you are using GeoGebra as a presentation tool, increasing the font size makes it easier for your audience to read text, labels, and algebraic input you are using.

Language

GeoGebra is multilingual and allows you to change the current language setting. This affects all input including command names and all output.

Note: No matter which language was selected, the globe icon will lead you back to the language menu. All language names are always displayed in English.

Graphics

This menu item opens a dialog where properties of the two Graphics Views (e. g. coordinate grid, axes, units, background color) can be set.

Note: You can also open this dialog window by right clicking (Mac OS: Ctrl‐click) on the Graphics View.

Perspectives

Save Settings

GeoGebra remembers your favorite settings (e. g., settings in the Options menu, current Toolbar and Graphics View settings) if you select Save settings in the Options menu.

Restore Default Settings

You can restore the default settings of GeoGebra using this menu item.
